Tuner Tuesday Dinan 5-off: 2008 M5 S2 5.8 6-speed v. 2001 540i 6-speed

I know that, amongst the authors that grace these pages, I seem to do a lot of comparisons of cars, some of which are extremely unlikely comparisons. One of our readers termed my picks a “Cheese and Chalk” competition; in many ways, he was right. After all, how can you really compare cars that are in completely different demographic categories? To be fair to me, I don’t always do such, but in that case that’s the appeal of the “10K Friday” series – taking a fixed budget and looking at the wild variety of cars that’s available simply because they’re similarly priced. However, I also like to compare similar vehicles and that’s the case today. I have two rare examples of Dinan-modded BMW 5-series. On the surface, they’re quite similar – both grey metallic, both with light grey interiors, both with normally aspirated motors, both have silver multi-spoke wheels with polished lips, and both have 6-speeds. But the level with which Dinan has breathed on them is quite different; consequently, one has double the power of the other, more technology and more complexity. That model also has one tenth the mileage of the other, and unsurprisingly is on offer at ten times the price making these seemingly very similar 5s very different. Which is the winner in your mind?

HUGE MSRP NEW $94,470.00!

Las Vegas Motorcars is proud to offer you this extremely limited chance of a lifetime at one of the rarest cars on the market period! This RARE 6-Speed Manual Transmission 628HP 2008 DINAN BMW M5 V10 BEAST is by far one of the hottest colors, heavily equipped/optioned and best upgraded of any M5 anywhere listed for sale! With over $180,000.00 invested in this car you are looking at a phenomenal deal! For peace of mind in purchase, this car is 100% fully documented and we have receipts for every single part that was installed on this car, there is no guessing game here! This miraculously upgraded M5 is a prior one-owner NON SMOKER car that was purchased brand new in Nevada and completely upgraded at the selling dealer which was Bill Pearce BMW. If you desire the ultimate driving machine, continue reading…I can assure you there is none quite like this one!

The exterior condition of this 628HP show stopping monster has been exclusively upgraded with a stunning yet subtle appeal which gives it a rare and exotic look that is impossible to find elsewhere. Sitting still the car looks like a stealth fighter going 200 MPH! (WHICH IT WILL EXCEED ON THE OPEN ROAD) Looking at our pictures and clear High Definition Video you will get a true sense of just how well this one has been kept. But to be honest, that’s just a sense, there is so much visual stimulation that you really must see the car in person to get an accurate feel for what you are truly looking at. The paint has a super high gloss to it with no major scratches , no dents and no dings. For a car with just over 13k miles we are baffled at how well this car has been preserved. We studied every inch of this car and cant find any prior damage, it appears all original which is hard to find in these days! Every aspect of the exterior was done in a very subtle and tasteful manner. The factory original wheels were upgraded with Forged Dinan 19″ Lightweight Staggered Wheels (With New Tires) to give it a more agressive look to enhance the appearance of the car without adding “bling” or weight to the car by using Forged wheels which actually reduced weight in return just shows how picky the prior owner was. There truly were no stones unturned when deciding the level of perfection/quality used to build what is the most tastefully done M5 that we’ve ever encountered and we have had many over the years with major upgrades! There are no signs of it ever being in an accident and our incredibly detailed inspection backs up all reports 100% and shows a great car with NO stories! All history reports are perfect & accident FREE including a Certified Carfax Report Vehicle History Report. All things considered you truly won’t find a better quality build M5 for the price point in which we are offering this car, for that matter I doubt there is a V10 MD anywhere in the world that really compares to this level of build…

The interior of this brute powerhouse has been left alone with a stellar amount of highly desirable color/fabric choices from the BMW factory with a stunning addition to the Silverstone II Merino Leather with some added Aluminum Trim to strike a gorgeous contrast to the interior. You won’t find any crazy boom boxes or wild audio systems in this car. The prior owner told us that the sound of the beastly 628HP 5.8L STROKER V10 DINAN engine was such an attraction that he just couldn’t bear to add to an already great sounding package. This M5 is a NON-SMOKERS car with no foul smells or signs of abuse and the only smell you will encounter is that of the properly treated leather inside the car. All of the surfaces are extremely clean and the seats are in excellent condition. To be honest it doesn’t look like there have been very many passengers in it, there were never any kids or car seats in the back and its obvious that it was very well kept by a car nut. I would imagine that if you spent over $180k on a car of this magnitude then you’d probably treat it pretty nice too, I know I would and it’s clear to see that this one is excellent in all respects.

From the moment you push the starter button your blood pressure will rise with the crackle of the DINAN built 5.8L Stroker V10 & DINAN exhaust as the deep growl that emits from the car in a surround sound style of way and it will have your anxiety level on edge. Chances are, you’ll start the car, blurp the throttle a touch or two then you’ll hop out and listen to all 10-cylinders purr with 628HP on tap that are ready to be unleashed! Jump back inside, strap yourself in and hold on, this car means pure business! This car has catalytic converters on it so it isn’t the obnoxious sound that you’ve heard from some of the uncorked M5’s out there. This car can be enjoyed with guests inside of it regardless if you are having work clients as passengers or your family. Once you calm down to a manageable level push the “M” button and hold on! As you can see and hear from the video, performance is out of this world and you’ll have no shortage of incredible memorable times in this car. Also keep in mind this car is slightly lower than a stock car and it handles much tighter and better than a stock car as well. If you want a car that runs and drives like an exotic race car yet fulfills the void of other life commitments that a 4-door provides then this is an easy choice!

If you’ve seen our feedback as of late you’ll notice that we sell rare exotics like this very quickly! Your options are slim due to the lack of availability on rare cars like this and fortunately for you this one is in stellar condition with very sensible upgrades to please anyone. Just check our 100% Positive eBay Feedback rating and see for yourself. We specialize in incredible finds just like this. Please feel free to bid with the utmost confidence and by all means call us for any further information. Thank you and good luck! Don’t let your dream car slip away…

Buyer Resources

Clearly, this is an M5 that the original owner had an open checkbook attitude towards. Taking the car to Dinan nearly doubled the original sticker price; arguably, a bad investment considering that resulted in only 125 horsepower more than stock from the upgraded 5.8 liter V10. However, the list of work performed is quite impressive and well documented. The last time I featured an E60, it was quickly shot down by most of the comments as an expensive Accord. To me, though, this one looks really special and well executed. It doesn’t do the normal trends like black wheels, for example, opting for the shining lip Dinan forged examples instead. Notably inside is the rare to find 6-speed manual; typically, the SMG transmission would have people running for the hills. That 6-speed normally means you didn’t get the trick rear differential, but this car has upgraded Dinan units coupled to that transmission, and as if the stock M5 suspension and brakes weren’t good enough they’ve also been worked over. Condition is absolute top and in line with the scant 13,000 miles covered, and the color combination isn’t outrageous but is certainly tasteful. The result is one super sleeper sedan, but also an extremely expensive one. Therein lies the problem; 628 horsepower used to sound massively impressive, but today a light change to the computers in a stock M5 will net the same power levels or more. Plus you could walk in to your BMW dealer and order a brand new M5, replete with warranty, for only about $20,000 more than this example. Granted, to some that’s a massive sum of money; but were I in the $80,000 price range on this car, I’d shop around to see if I could get a bit more financing and get a brand new M5. They’re better looking, faster, come with a warranty and you can pick the color that you want. You can still even opt for a 6-speed manual. This car is impressive, but it’ll take one seriously devoted M5 fan that likes Dinan cars to get into this one.

CLICK FOR DETAILS: 2001 BMW 540i Sport on eBay

Year: 2001
Model: 540i Sport
Engine: 4.4 liter V8
Transmission: 6-speed manual
Mileage: 153,000 mi
Price: No Reserve Auction

2001 BMW 540i “DINAN 5” M-Sport 6-Speed Manual

Authentic DINAN-badged 540i with:

Dinan Stage IV Engine Software
Cold Air Take
High Flow Throttle Body
High Flow Air Mass Meter
Slotted Brake Rotors

Estimated 335 horsepower, versus 290 for stock car. Very quick, wonderful engine sound. When I purchased the car, I called Dinan to confirm the upgrades and was told it was a badged car, and the rep sent me a new Dinan 5 badge, since part of it was missing from the car. The original owner did the DINAN modifications, and I am the 3rd owner.

In addition to the Dinan modifications, the car has:

Custom, “piano black” wood trim (minor cracks, customary for age)
BMW “M” shifter
Instrument cluster silver gauge rings
Euro-style headlights with angel eyes and clear corners
BBS BMW “Style 19” wheels (2-piece, very light weight) with polished rims and near-new tires- square setup
Akebono brake pads (about a year old). Great feel and no brake dust!

Anthracite with gray interior, 6-speed manual, comfort seats, front & rear parking sensors (“PDC”), CD.

Overall, the car is in very good condition with a couple imperfections (see pictures) and a few scratches. No rust. Interior is very clean with no rips and minimal wear on the seats. There is the usual pixelation issue on two of the cluster readouts (odometer & temperature)- please see picture. When I purchased the car, I used the Leatherique Restoration System and put new floor mats in.

The car is mechanically sound. There were a few issues discovered on the PPI when I purchased the car 15 months ago, most of which I corrected:

Power steering hose needed replacement- replaced, new fluid, new rings
Brake hoses needed replacement- replaced, new brake fluid
Rear control arms had too much play- replaced.
ALSO DONE: Fuel filter replaced, Rear Diff & Transmission fluids changed. Oil (LiquiMoly) changed.

The valve cover gaskets were seeping just a little oil, but the issue was so minor I did not replace the gaskets. The coolant was slightly dirty but seemed okay, so I did not have flushed.

So, the car really needs nothing, except for the two items listed at some point. I have never had a SES light come in since I have owned the car.

The car drives perfectly- very powerful and smooth. No creaks or squeaks, and no vibration. It is a pure pleasure to drive. Why am I selling? Regrettably, I have developed a left foot problem, and it is now uncomfortable for me to drive a manual transmission with a clutch.

Vehicle is sold AS-IS with no warranties. Buyer is responsible for shipping. I am happy to help with shipment, such as driving to a DAS drop-off point near Richmond. Oil changed 300 miles ago. I have service records, both keys, and all manuals.

Deposit of $500 due with 48 hours of auction end. Clear title in hand.

Nice examples of these cars with a 6-speed are getting rare. I encourage anyone interested to arrange a PPI (I will gladly assist) and a test drive. Please send me a message with any questions. Thank you!

Here’s the recipe that most seem to want; the E39 sedan that most love, a 6-speed manual mated to the pretty potent M62 V8, original condition and a list of reasonable Dinan mods that neither break the bank nor the motor. Sure, this car isn’t as much of a pinup and probably wouldn’t draw a crowd like the M5 would at a ‘Cars and Coffee’ event, but then you could buy much more coffee with the $72,000 you’d saved. That’s because right now this example is available at no reserve for much more reasonable $7,500 (current bid, no reserve, no bids at time of writing). To me, the big attraction here is the not often seen Style 19 BBS multi-piece wheels in great shape. They’re lovely and I always liked them. The condition looks to be very good on what is now amazingly a 14 year old car and the color combination is classic without being cliche. It’s also offered by a seller who apparently did their homework, something that is appreciated by enthusiasts.

Which is the winner? While the heavily modded Dinan 5.8 V10 M5 S2 will grab the headlines (or did, a generation ago), to me the value of the much more affordable and arguably more usable E39 is undeniable here. Besides being better looking than the E60, you simply can’t extract the performance of the over 600 horsepower V10 easily on these shores. On the other hand, you can enjoy revving out that E39 much more legally and despite the much higher mileage you’ll still have a good condition and classic BMW to enjoy.

I wouldn’t mind taking the M5 for a spin, though….

    I hope you didn’t take my “Cheese and Chalk” comment as a slight – because I like those types of discussions. They are far more imaginative than “Cheese and Cheese”.
    Having said that – take the E39, enjoy the ride, and save the extra +$60K for when the current F10 M5 hits the used car lots.

    @Vic, not at all! To the contrary, I really appreciate it when people take the time to contribute their opinions (and facts) because I think it leads to a much more interesting dialogue. Speaking of which, my original Volkswagen choice would have made an even more outrageous comparison; I had found a clean Mk.1 GTi for $9,500, but I decided it was really too far outside reason to compare that car to the Merc. Anyway, as always glad I prompted a discussion and I agree with you on the 5s!

    while the E60 stroker is an impression motor….I don’t see that car trading for anywhere near that ask….
    while DINAN is considered one of the best folks out there…its no secret that you will lose 50/60% of your cost easy when its time to resell…that’s the nature of modifying a car…
    that said…I think your forced to pick the 540 just from a cost perspective….even though it will be painfully slow when compared to the E60….the cost diff. is just too great….
    as a side note…the S85 is as close as you will come to hearing an F1 noise coming from your car…
    they really sound amazing……

    Gosh, guess I was wrong – not the first time. Someone bought the M5 at full price. Must be nice!
