1985 BMW 535i

A while back I wrote up a very interesting Taiga Green 535is that had a lot of miles but was still an eye-catcher. Today we have a similar situation – a passed-down E28 with a lot of miles but also a lot of love, resprayed in an attractive viridescent hue. It’s a little scary when you look underneath, but if you keep your eyes up you’ll find a clean E28 that looks great in a unique color with shadowline trim and a black interior. If you believe the seller’s history and are ready to continue stewardship (i.e. fixing endless little issues) on this classic, it could be a good looker for the money.

1995 BMW M3 Dinan S3


The E36 M3 was lauded as one of the greatest handling cars of all time, but those of us in the US were always a little disappointed that the M3 made due with 240hp here throughout its lifespan, while the Euros ended up with a 321hp beast that makes the E46 seem like a lot less of a leap than it was here. There were many ways to go about fixing the lack of power, but few are more reputable and holistic than Dinan’s packages. With just an intake, chip, and exhaust, the first M3 I drove had a healthy dose of aggression. Today’s comes with the full meal deal, earning the Dinan badge and a Euro-shaming 340hp out of the supercharged 3.0l. That’ll be plenty for me, and it carries the bigger stick without raising its voice, just some Dinan blocks at each corner. This example is cherry in color and condition, having covered just 38k miles. With BMW’s endorsement of Dinan, examples like this may well become the most sought-after, especially when they are this well cared for.

Tuner Tuesday: BMW Dinan ISR3

Steve Dinan is a wizard at building monster BMWs, and as such managed to make it into the inner-circle as a dealer-approved modifier of BMWs. This extends not only to the base models but also to the already specialized and quick M models. No one who has driven a M Roadster will accuse it of being a slow car, but Dinan took the S52 motor to another level by adding a supercharger and a host of engine and exhaust upgrades to match. But it didn’t just end there; Dinan revised the suspension as well to better suit the increased power and offer more adjustability to the owners of these specialized cars. One aspect that I think is particularly nice about Dinan’s creations is that they often retain the mostly-stock look that makes sleeper performance cars so special. Plop that performance into a M Roadster and you have a ton of top-down fun:

One Owner – Great Condition – Supercharged – Intercooled – Enhanced Low Back pressure Exhaust – Enhanced Suspension & Much More… This is Monster Road Machine in an M Roadster body! Check out the Road & Track and Roundel articles on this car – Internet links below.

Only 6 of these Supercars were made and even fewer are still in existence. This Dinan ISR3 was the 4th BMW M Roadster converted (out of a total of only 6 ISR3 cars created by Dinan Engineering).

Extra Options Added beyond ISR3 Conversion:

Removable BMW Hard Top with rear glass window w/electric defroster/ rolling hard top storage stand

BMW Two-Tone Electric Leather Seats
Dinan Carpeted Mats

Dinan Boost Gauge: Shows Supercharger Overpressure

Escort 9500 Stealth Built-In Front/Rear Radar/Laser Detectors With Laser Jamming

In-Line 3.2 Liter Six Cylinder Engine
5-Speed Manual Transmission
Blue Soft-Top Excellent Condition
AM/FM Stereo/CD Player
Heated Blue Leather Two-Tone Seats
Cruise Control
Tonneo cover
Wind Screen

Each Dinan ISR3 conversion began with a new 2000 BMW M Roadster, which was in-turn superbly modified by Dinan in the following ways:

Engine: intercooled supercharged DOHC 24-valve 6-in-line straight six; aluminum block and head, Dinan/Siemens engine-control system with port fuel injection; Vortech helical-cut-gear-driven supercharger for quiet reliability; 10 pounds boost into 10.5:1 compression; 50-state emissions legal. Two different sized compressor bypass valves, one before and one after the intercooler to eliminate low-speed stumble and surging typical
with “high boost” aftermarket supercharger systems. Thermostatically controlled engine oil cooler, enhanced fuel delivery system with larger high-flow fuel injectors. Air filter located outside engine compartment to insure exposure to cool, dense air. Integrated bumper ducting provides ram air effect as road speed increases.

Displacement: 192 cu in, 3152cc
Power (SAE net): 396 bhp @ 6500 rpm
Torque (SAE net): 326 lb-ft @ 5500 rpm

High Flow Throttle Body: Internal diameter of throttle body has been increased for improved airflow. Throttle response is also faster as a result of the modified shape.

High-Flow Air Flow Meter: A larger-diameter air-flow meter is included in order to improve Intake airflow efficiency. The design incorporates a unique “labyrinth” for improved air-flow-meter-voltage stability as well as shielding it from cylinder pulses for a smooth idle and improved peak horsepower.

High Flow Intake Manifold: Polished and ported with larger-diameter intake runners for maximum intake efficiency and resulting power gains.

Engine Management System: The Siemens engine-management system has been programmed for maximum power gains, drive ability, and emissions compliance. System maintains all “On Board Diagnostic”

(OBD II) functions and ignition timing and air/fuel mixtures are optimal throughout the engine’s operating range. VANOS (variable cam timing system) has been reprogrammed for maximum power gains throughout the engine’s operating range.

Free Flow Exhaust: Stainless steel, free-flow mufflers insure that backpressure is kept to a minimum, without creating an unacceptable exhaust note.

Clutch: Stock “dual mass” flywheel and clutch assembly replaced with Dinan Stage 2 Clutch Assembly. Lightweight aluminum flywheel reduces clutch weight by nearly 15 Ibs. or 39%. Clutch clamp pressure increased by 20%.

Transmission: 5-speed manual

3.38:1 Limited-Slip Differential: Final-drive gearing has been lowered from the stock 3.23:1 ratio to compensate for the increased outer diameter of 285/40-17 tires in the rear.

Performance Springs: Increased spring rates and a modestly lower ride height provide greater control and traction in turns.

Moni/Dinan Externally Adjustable Struts and Shocks: Matched with Dinan springs for maximum control. Features custom digressive compression valving for more low-speed shock shaft velocity control, providing greater restriction of camber and toe-angle changes. Front struts are externally adjustable for personalized control of ride quality and handling characteristics

Anti-roll Bars: 22mm front and rear adjustable anti roll bars.

Front Camber Plates: Relocate strut pick-up points for two degrees negative camber in the front, greatly improving turn-in.

Camber Adjustable Rear Subframe: Provides adjustment of camber angles at the rear of the car.

Front Strut Tower Brace: Reduces flex at the shock towers for sharper handling.

Wheels and Tires:

Front: 1 7×8.5″ Dinan Three-piece modular wheels, 255/40-17 Michelin ZR Pilot Sport tires.

Rear: 1 7×9.5″ Dinan Three-piece modular wheels, 285/40-17 Michelin ZR Pilot Sport tires.

Brakes: Brake pads replaced with carbon/metallic pads.

There aren’t many of these little rockets floating around – the original article from 2001 claims that only 50 would be built. With 400 hp on tap, they’re a potent package, too. Of course, that potency cost, and cost dearly; new out the door, these Z M Roadsters boasted price tags in excess of $80,000 if you ticked all the right boxes. Sound like a lot? It was, because shortly after the launch you could get into a 315 hp S54-motored Z M for around $45,000. The question then becomes one of exclusivity; do you want what no one else has? Perhaps, and if that’s the case then this car is a good candidate for you.

Of course, it sure would be nice if the seller provided better pictures and some more information, specifically on the claim that the car is only one of 6 (though, I’m guessing perhaps in that color?). Though it has low miles, no mechanical history is provided of the car. Then there’s the asking price – $50,000, which by my maths will buy you no less than three normal M Roadsters with change left over to spare. Much like last week’s Ruf 3400 I think the asking price is far too high even considering the increase in performance. While I have no doubt the car is quick and rare, I just could never justify that sort of premium for this particular car.


Tuner Tuesday: 2008 BMW M3 Dinan/Hartge

In the wonderful world of tuning, there’s taking it to the edge, and then there’s stepping over the edge. For every tasteful example of a tuner-modified car, it seems that there are several that take it one (or many) steps too far, creating a bit of a monstrosity in the process. While modifying cars is and will always be a form of individual expression, tuning firms always attempt to produce what will sell, not necessarily what is in the best taste. In the spirit of this, today I want to look at a car which I feel was taken a few steps too far; a 2008 Dinan and Hartge modified M3:

Indeed this is not your ordinary M3, and I was able to write that without caps lock on. In fact, I don’t think you’d need to write that this wasn’t your ordinary M3 if you just look at it. There are so many items that are to like here, and well engineered components at that. First, there’s the superb M3, made even more superb in the beautiful shade of Interlagos Blue. You could have stopped there, and I would have been sold. Then there are the Dinan upgrades; well, who doesn’t like a bit more power? How about one hundred bits? The Dinan upgrades also extend to the transmission reflash and rear end. Okay, I’m still on board. We move on to the Active Autowerks exhaust. I’ve heard these cars opened up, and it’s pretty glorious. Haven’t lost me yet.

Then there are the Hartge bits; wheels, rockers, bumper add-ons and roof spoiler. It’s here where I start to loose some enthusiasm for this build; these items are a bit too blingy and take a bit away from the understated performance of this car. Still, they’re Hartge pieces, and that carries some weight, so I’m not completely lost. However, the shouty “Hartge” custom graphics, the custom painted engine cover, the pedal set, badges everywhere….I just don’t know, it seems akin to digitally inserting Jabba the Hutt into the original Star Wars. Does it add anything? No, you’re just sitting there saying “Okay, I get it, you just wanted to show off that you have money and can do whatever you want”. It goes even farther downhill for me from there, with a few more badges and names thrown into the pile. It’s as if the owner decided to make a sunday at Cold Stone Creamery and added every single item from the toppings menu. Sure, it may taste great for a bite, but in the end you just have a brown pool of melted ice cream with gummy bears and soggy oreo bits floating all over.

While I have no doubt that the asking price of this car doesn’t come close to claimed $100K build costs, the reality is that I don’t really see much value in this car over a stock ZCP car. For all it’s Hartge bragging it’s not a Hartge, and doesn’t identify as a Dinan either, and that leaves it a bit of a “dog’s breakfast” to quote Clarkson. That’s sad because it has all of the right ingredients; I just really wish they hadn’t dumped all of them in at the same time. What do you think?


2001 BMW M5 Dinan S2

There is something rather sinister about a black E39 M5. The E39 was always a car with a certain hard edge to it and in black that edge is taken to another level. As someone with a particular fondness for black cars, this M5 hits all of the right notes for me in its appearance. In addition to its sinister appearance, this 2001 M5 has received the Dinan treatment, making what was already an excellent engine into something that is truly special. The Dinan engineers were able to induce an additional 76 hp with the S2 package without resorting to forced induction. Airflow was improved along the entire length of the engine’s breathing system, beginning with a revised air intake and culminating in a redesigned exhaust that is both lighter and helps produce more power. This car has received the entire S2 package with the exception of the wheels and brakes. Having the brake treatment done would have been nice, but I prefer the stock M5 wheels over those in the Dinan package, especially on a black car such as this one, so I wouldn’t consider that portion a loss. Overall, what we have here is a car with extra aggressive looks and the additional power to back up that increased aggressiveness.

Up for auction is a very interesting M5……I acquired this car recently from a customer as part of a trade for a car I had that he wanted. I planned on keeping it as my daily driver but things have changed and I’m forced to sell. I’ve been working on this car since 2003 when it had 14,000 miles on it. My shop performed all the DINAN upgrades(authorized DINAN dealer for the last 12 years) and has done all the major maintenance on the car (E39 M5s/540s are one of our specialties). The DINAN S2 package was installed in 2004….this is the full S2 package minus the DINAN lightweight wheels and brakes. The car was sold by the original owner in 2006 to a family member where it covered about 30,000 miles then it was then sold to a non-family member who covered about 45,000 miles in the 2 years he had it(purchased in late 2010). In that time we did a TON of work on this car as he was completely OCD about the car…every rattle, chirp, noise, leak was addressed and corrected. I have $22,000 in invoices that was spent on this car with the bulk being a 56,000 mile motor swap that was performed when the original motor damaged a rod bearing. We decided to install the best low mileage used motor we could find($7500 motor, 35 hours of labor, $2000 in OEM parts).

The car is in very good shape for a 12 year old car but it’s a been a driver vs. a garage queen. There are rock chips on the forward edge of the hood, there’s a 2″x3″ scrape on the lower right front bumper(touched up). There are pixels that are out on the dash, the rear view mirror needs to be replaced for the auto dimming to work). Rear Hankook tires are at about 30% tread remaining. Interior is very clean in this car….it has been my experience in these cars that have the black luxury interiors hold up very well compared to the other colors/styles. The wood trim was painted a satin metallic grey(BMW Sterling Grey) a long time ago….looks very nice. The shifter knob has some wear on it. I have a nice set of OEM floormats for the car. Car has it’s books/manuals and I saw an extra key in it’s book binder. The owner I purchased it from had the clear rear turn signals blacked out which can be returned to stock. Front headlights are the euro units which are in pretty good shape for their age(we installed those back in 2004 along with painting all the OEM trim gloss black, painting the grilles, etc.). Everything functions as it should on the car at this time.

In addition to the standard DINAN S2 package, this car has the DINAN/JRZ shocks/struts on it. They were just returned to DINAN and rebuilt within the last 6 months. These ride much better than the DINAN Koni shocks/struts. They’re fully adjustable as well. If memory serves right, they were about $800 EACH as an upgrade to the DINAN stage 2 Koni suspension.

Service/maintenance highlights over the last 2 years include:

56,000 mile engine installed at 103k miles. Cam position sensors (common failure in these cars) were replaced (all 4), all the normal gaskets, rear main and front crank seals (front crank seals are known to leak), all fluids of course, breather hoses, etc., were replaced during this job This was a $13k job. Car runs flawlessly and has no check engine light or known issues.

New high flow catalysts were installed along with OEM BMW 02 sensors, new thermostat, new DINAN cold air intake filters, new electronic box fan assembly

Air flow meters have been replaced

MK3 navigation drive unit installed

Differential bushings(uppers and front)

Rear CV joint(driveshaft) and drive shaft bushing

Transmission fluid with BMW MTL-2(lifetime fluid)

As I’ve said, I know this car pretty well….it’s been a great car. It drives perfectly, has had all the normal M5 issues taken care of and has that all-impressive DINAN S2 package. I’ve owned several of these cars as my personal rides (specifically the S2 cars) and they remain to this day as one of my favorite cars to drive. The standard M5 is tremendous, a DINAN S2 M5 is from out of this world.

I’m more than happy to respond to emails. I will gladly provide additional pics if desired.


The seller has provided quite a bit of detail and his knowledge of the car suggests that he would be capable of answering any questions a particular buyer might have. This car has a few flaws but for a car with just a bit over 100K miles, it still looks in fine condition. Bidding is currently at $15,251 with the reserve still on. With E39 prices on the rise and this car coming with a bit of extra specialness we’re almost certainly going to see the bidding come up. The last E39 M5 I profiled sold for $30,000. That car was much lower mileage and nearly flawless. Will the Dinan package on this car counteract the increased mileage and see a similar selling price? I’m honestly not sure, but this car is going to provide someone with a brutally sinister saloon.


2005 Dinan S3 BMW M3

When I wrote up yesterday’s 2002 Dinan S3-R M3, I wanted to find an equivalent model to it for sale for value comparison. Naturally, I think the best counterpoint would be a lower mile late build E46 M3 equipped with the ZHP competition package, the hardest-edged M3 available without modification in the U.S.. To my surprise, I found an even better comparison; a ZCP equipped M3 with enough modifications to get a Dinan registration, but without the supercharger and suspension rework of the S3-R. Today’s example looks ready to race in Imola Red:

The ZCP Competition Package on the M3 added some nice details, but in my eye the best of those is by far the wheels. Those BBS 19” wheels transform the car’s look to be both prettier and more aggressive at the same time. There are some modifications to add some power – the exhaust sounds great, the throttle bodies add a few horsepower, and the 3.91 rear end gives you a bit better acceleration, but to me these modifications don’t really alter the M3’s basic characteristics, unlike the supercharger addition in the S3-R. Imola Red fits the character of the M3 well and is one of the prettier reds available on any car, although I still don’t understand why anyone would spec a car with black leather. This car with caramel leather, or better yet Imola leather, would just put it over the top in my opinion. As is, though, the car presents very well and looks to be in fabulous shape.

Both the 2002 Dinan S3-R M3 and this car are priced right at the top of the E46 market. One of the long term benefits of not having the supercharger is less wear on the transmission (in my mind, a big benefit with the SMG) and perhaps a less expensive engine rebuild/replacement if you owned it long enough. To me, that’s probably a good enough trade off for the loss of acceleration. I don’t think the Dinan registration helps the value short or long term on this vehicle, but I also don’t really think the modifications detract from the value and are pretty easily reversible if you wanted to revert to stock specification. Which would you rather have?


2002 Dinan S3-R BMW M3

Tuner cars can be the stuff of dreams when they’re done right, and the subject of nightmares when gone wrong. Many tuners bolt of ton of parts onto a car, slap some stickers on it, and to be damned with what happens in 10,000 miles – they’ll be onto the next photo shoot. Some select tuners, though, are so good at their craft that the German factories recognize their work as up to their standards. Most of these tuners reside in Germany, but a few have popped up in the United States. Dinan is one such company, good enough at their craft to be recognized by the factory and have the modifications available directly from the dealerships. To be that good requires massive trial and development which comes at a serious cost – fully spec out a Dinan S3-R, and you more than doubled the original list price. The results were as impressive as the list price – 460 horsepower pumping out of the 3.2 M3 inline-6 put the M3 into 911 Turbo speed territory. Today you can pick up one of these rare rockets for about a third of the original asking price – such as today’s Topaz Blue 2002 model:

You read that right – $68,000 in modifications on a $56,000 car. It’s hard to imagine anyone would tick all of the option boxes as that puts you into some rarified pricing, but a few brave individuals with deep pockets did. The build sheet reads like a racer’s Christmas wish list. While some cars can really look over the top, Dinan has stuck with an understated look – from the outside, it’s just about impossible to tell that this car has nearly 50% more power than a stock model. The Dinan alloys are very pretty and suit the design well, and Topaz Blue is one of the more rare colors to find on the E46 M3. The car appears to be well cared for and in fantastic shape.

Now, the price is admittedly pretty steep, but the performance level puts you into another level entirely. The big question is would you pay the best part of $40,000 for a 11 year old tuner car? The price compares similarly to B7 RS4 or late build Competition Package E46 M3s with low mileage. Is this the car to buy? I guess that depends on your goals buying a used M3. Want to slap a bunch of modifications onto an E46 M3? This is a better way to do it, because it’s got all of the right and well developed modifications. Want a more reliable mostly stock M3? Than no, this isn’t the car for you. You could easily drop $10,000 – $15,000 into a $20,000 plus M3, and not have a car that is as nice as this. But most people looking to modify the car look for lower priced examples, and most people looking to collect or drive long-term look for more stock examples. I’d be worried that the SMG wouldn’t be up to the task of dealing with the power long term. The future will tell if collectors will be pining after Dinans like they currently do for clean Alpinas and Rufs. What do you think – is the S3-R worth the purchase price?

The below post originally appeared on our site May 8, 2013:

If it walks like a duck and talks like a duck…it must be a duck, right? Not necessarily. At first look, you’d see a clean M5, but then look closer and you see a clean 530i with the Dinan treatment. While the M5 is an all out performance sedan, this Dinan 5 is more of a gentleman’s sedan with a touch of sport.


On a lot of levels this car falls short of the M5, but on other levels, this car is just as good. The smooth and torquey V8 is a bit more civilized compared to the high strung six in the M5 and with the Dinan upgrades, the power gap becomes a lot less. Add in the smoother suspension and plush interior, and this car offers a great alternative to the increasingly pricey E34 M5. This beautifully maintained 530i for sale in Pleasanton, CA is a great daily sedan.

This BMW came to us, as do the majority of our cars, from one of our very good customers. We have been dealing with this customer / friend for years and he regularly arrives at our showroom in some very interesting German sports cars and sporting sedans. One day, he arrived in this great BMW indicating that he had purchased another “toy” and that something had to go ( and he didn’t want it to be his marriage!). We drove the BMW DINAN, fell in love and, as they say, the rest is history.

For over 2 years, the “Dinan 5” has been an occasional use car by our owner when 2 seaters and SUV’s are not being used. The BMW is a practical yet fun car to drive and represents a truly wonderful sporting sedan. This 530i is factory equipped with the strong 3.0 liter V8 that offers excellent performance in addition to very good fuel economy in part as a result of the cars manual 5-speed transmission. The BMW has had no major mechanical modifications and the DINAN upgrades have not negatively affected the BMW’s comfort for five, great handling, sporty 5-speed and even very good fuel economy! Perhaps the best part is that this generation E34 cars represent a tremendous value, especially if well maintained, low mileage cars can be located. This car is one such example.

With meticulously kept service records, relatively low miles and tasteful upgrades, this is a great car for someone looking to drive an older sedan. This car is selling in a reserve auction and I would expect that it sells in the $6,500 ballpark. That’s much less than an M5 of the same caliber, with just about the same looks.


2006 MINI Cooper S Dinan

A little more than two years on, I’m still enamored with my 2006 MINI Cooper S. I was lucky to stumble upon my Astro Black (dark metallic blue) R53 at a used car lot outside of Philadelphia with a scant 33,000 miles on the clock. I am just about to turn 45,000 miles, because I take public transport to work, using the car simply on weekends and road trips. Every time I get behind the wheel, this car puts a smile on my face in every gear.

Since 2006, the MINI lineup has grown a lot larger, much to some purists’ chagrin. Like the Porsche Panamera and Cayenne, I understand cars like the MINI Countryman and Paceman have their time and place, but for me, only a Cooper will do. We haven’t featured an R53 in a while here on GCFSB, but this Cooper S for sale in Florida has some nice Dinan upgrades and is making the right noises.

Year: 2006
Model: Cooper S Dinan
Engine: 1.6 liter supercharged inline four
Transmission: 6-speed manual
Mileage: 72,000
Price: $14,900

2006 MINI Cooper S Dinan on BMW CCA Classifieds

Stunning example of the last year supercharged R53. Fully optioned: Cold weather pkg, Premium pkg, Sport pkg, limited slip differential, HK sound plus more. 206 HP Dinan S2/S3 upgrades, too numerous to list. Outstanding condition. Second owner, have owned for six years. CA car since new, no accidents or repaint. Never raced, tracked or abused. Complete documented maintenance records. Email for full fact sheet.

When I bought my Cooper S in early 2011, I paid just a hair over $15,000. My car is a base Cooper S without the Sport Package or Premium Package, but it does have the Cold Weather Package. The mileage on my car is still much lower than this example, but in all honesty, this souped up Cooper S certainly looks just as mint as mine. I’d say this car’s extra features and power are evened out by the lower mileage on my car. So after two years then, we’re just about even when it comes to depreciation? Probably not. But at this asking price, we’re not that far off. I’m guessing this car would probably shift for somewhere between $13,500 to $14,500.


2007 BMW 335i Convertible

Over the past fifteen years or so, BMW’s lineup has transformed from a relatively simple lineup with the 3, 5 and 7 series at its core to a vast mix of SUVs, roadsters, the compact 1 series and the MINI lineup which shares ultimate driving machine’s DNA. One popular constant, though, has been the 3 series convertible.

The first 3 series convertibles that appeared were conversions by Karosserie Baur on the E21 and E30 chassis that had integral roll hoops and fixed rear windows. Then in 1987, the 325i convertible appeared on US shores, a factory produced model that became an instant hit across a number of demographics and was featured prominently in a number of television series and movies of the era. Over the years, the 3 series convertible became larger and more powerful, morphing into the retractible hardtop convertible we have today. While some lament the heavier weight of always having a hardtop to lug around, the all-weather practicality is attractive, particularly for those in colder climates who still enjoy al fresco motoring from time to time.

The following 335i Convertible with Dinan mods comes to us from our reader Andrew, who’s father has listed it for sale in California.

Year: 2007
Model: 335i Cabriolet
Engine: 3.0 liter twin turbocharged inline six
Transmission: 6-speed manual
Mileage: 44,500 miles
Price: $33,000

2007 BMW 335i Cabriolet on M3Post

Posting for my dad, who takes better care of his cars than anyone I’ve ever met. He wrote the following:

2007 BMW 335i Convertible in Black over Saddle leather. 6 speed manual, 44,500 miles. If it were not for Sciatica and weakness down my left leg I’d never sell this car! This car is now what the 335i should have been from the factory!

All factory bulletins are up to date and, to protect the buyer, this vehicle has BMW’s best warranty until 100K miles or 03/2014. Every button, switch and knob works perfectly and the car needs absolutely no service whatsoever! The car is kept clayed and waxed. The leather is cleaned and treated so the interior shows almost no wear and the car is in our garage when it’s not driven.

No dents, no dings, no accidents, kids, pets or smoking. Tires (never coated or “shined”) are Michelin’s best Pilot Sport 2’s as 235/40/18’s in the front and 265/35/18’s in the rear, on CSL replica wheels. This sale includes the original BMW wheels and run-flat tires.

Dinan’s 100% reliable modifications (installed by Dinan, Temecula) give it low end torque so turbo lag is gone and acceleration is smooth and easy. The exhaust note is automobile “music” and the UUC short shifter is a delight. This car has never been raced or “tracked” (I’m over 70!), but I sure love to drive great cars and just one drive in this 335i will convince you I’m right. Folks tell me how great this convertible looks, all the time.

The seats are perfect and putting the hard top down just makes my day. No IDRIVE so everything works without a fuss. Mileage did not change with the Dinan upgrades as 18/27 is about right. A list of what’s in this 335i includes but is not limited to:

– Debadged
– Tinted windows
– “Ultimate Pedals” solid aluminum pedals,
– “X-pel” headlight protectors, all new hoses (done by BMW),
– Premium Comfort & Sport Pkgs.,
– Hill-Hold, Bluetooth, keyless entry, power/heated seats,
– Complete overhaul of the factory radio (fading of its display is a known BMW problem!),
– Dinan ECU programming, air intake system, stainless steel exhaust & a UUC solid stainless short shifter & DSSR.

If what you’re looking to own and drive is a superb 335i convertible, this is the only one to consider. Period.

$33k obo. Car is located in Palm Springs, California.

It’s rather refreshing to see one of these convertible E90s with a 6-speed manual transmission. If I had to guess, I’d suspect at least 85 to 90% of all E90 3 series convertibles that have been sold in the US have been automatics. While the convertible isn’t the outright sporting choice for the hardcore driving enthusiast, this 335i looks pretty purposeful in black with the CSL style wheels. Add in the Dinan upgrades, and it makes for one tasty 3 series. The E90 convertible was never really my cup of tea, but if I was going to own one, it would be this exact car.
