Hooniverse led me to this eBay ad, selling a 1984 533i with a Dinan turbo system. I love E28s with their could-only-come-from-the-80s styling. Whether it’s the best looking 5 series is a matter of personal preference, but the negative rake on the front and rear and the pronounced Hofmeister kink reek of good times with 80s junk bond money and listening to Genesis. I can’t quite wrap my head around the Dinan work on this one… 400 hp out of a 533i? Terrifying. The bonus here is that if you bump into something, it comes with a running parts car! I like the 535is a lot with its M5ish body kit, and free is a great price, even if it has an automatic.
The Dinan car looks to be in good condition inside and out, though the body kit from the 535is/M5 would make it much sexier without losing much of its sleeper status. The engine bay is amazingly clean, though 183k miles on a turbo engine, even the solid M30, is a lot. The 535is looks fine if a little rough, also having worked its way pretty far up the odometer.
This is not going to be a work-free purchase. That doesn’t mean it’s a bad one; if you’re prepared/experienced for some E28 maintenance, this could be an awesome find. I can’t help thinking the Dinan car would be better served if it were advertised by itself, as I spent more time confused by the weird 2-for-1 deal than in awe of a 400hp E28. Also weird, though cool, is the option to choose what wheels come on the cars (go for the BBSs!). Weirdness aside, they’re cool cars that could give someone a fun time, though they sit on eBay at $8,000 at time of writing with no bids and 2 days remaining.
We’ve seen how the market treats previous generation factory Dinan M5s well, here is a chance for a more recent take. You’ve seen it all before, someone selling a “Dinan” BMW, when really all the car has is maybe a couple bolt on bits the owner slapped on in their driveway along with a Dinan badge. This however is what happens when the work is done by professionals paid for by someone with deep pockets.
This E60 has Dinan’s S3 stroker kit under the hood. Which takes the 5.0 liter V-10 up to 5.7 liters and 628 hp and 482 lb-ft of torque. This upgrade will set you back a cool $40,000. This particular M5 also has another $30,000 put into Dinan intake, suspension, and exhaust work. So what you have here is an owner who wanted an ultimate 4 door sedan and was comfortable dropping around $200k to get there.
The car does look good in its Indianapolis red paint scheme (and I’m not a fan of red cars), the body color matched red line wheels are a nice touch.
Built in radar detection is clearly a must. What really set this car into the drivers category is that the owner decided to go with the 6 speed manual instead of sticking with the more popular SMG transmission. True enthusiasts will really find this a plus. I can’t help, but think that with all that extra power the SMG might make life a lot easier if this was to be a daily driver as opposed to weekend escape car.
The dealership selling the car, Chicago Motor Cars has all the receipts for the work done which should help the sale. With a buy it now price of $89,800 a new owner can take home this under 20,000 mile car and basically get almost $100,000 of top notch custom parts and labor for free. The only slight draw back is unlike some other Dinan parts the S3 kit does void the factory warranty and the Dinan warranty only provides two years of coverage. Still with a well established company like Dinan and reputable installers Performing Imports out of Alpharetta, Georgia, you can be assured that the intention was for this vehicle to have a long life if maintained and not abused. Be advised though in terms of maintenance, one of the receipts shows that just a simple oil and filter change cost $239.

Here is a video from the folks at Dinan showing the V-10 Stage 3 kit and what it can do:
It is a full Euro spec car with only 24,000 miles. It has Dinan add ons including Stage III suspension, intercooled turbocharger, Borla exhaust, and Brembo brakes. Quite a bump up in horsepower from the stock Euro trim 286. One owner cars like this don’t turn up all that often.
I always have a soft spot for vehicles that once held the title fastest production sedan in the world.
Mercedes and BMW sure had the cool headlight wiper thing figured out. The twin arm design on the M5 is similar to that found in vertical orientation on another fastest sedan in the world, (and perhaps godfather of all the German Q cars) the 300SEL 6.3.
I’m not really sure if the modifications made to the car hurt its collectible value. I doubt it since they are contemporary with the time the car was new and done by a reputable BMW tuner.
Its expensive at a priced reduced $29,900, but I wouldn’t mind having it in my garage for sure. Its listed in Hemmings at $31,900.
From the seller:
1986 BMW M5. European specification model. Only 24,000 original miles! This superb example features flawless “Diamond black” paint with gorgeous brown water buffalo leather. With only one owner from new, this Dinan-prepared M5 features an inter-cooled turbocharger and Borla stainless exhaust system, the combination of which produces an impressive 462 horsepower! A stage III suspension package and Brembo F-40 braking system with drilled rotors makes this a true “Ultimate Driving Machine” experience. In addition, thermostatically controlled transmission and differential coolers have been fitted to the car. The usual 5-series amenities of air conditioning, power windows, door locks and factory sunroof add to the comfort and convenience of this ultra-high performance sedan – a true sports car with four doors. All EPA and DOT certification papers are available.
Our M5 was imported by its one and only owner and all certification paperwork comes with the car. Even the original German ownership document is available! All upgrades were completed in California by Dinan, the preeminent company for BMW performance enhancements. The turbocharger brings the horsepower up to 462! The differential has been converted to a 3:91 from the original 3:73. New clutch in 2005 and the turbo was rebuilt in 2006. Split Second control for air/fuel mixture has been installed in lieu of the air flow meter. Surely this is among the finest, lowest mileage early M5’s anywhere and could certainly be unique with its upgrades. Lastly, the car has been thoroughly inspected and completely detailed by the TLD staff.
For those of you who know, this car needs no introduction. For those of you who don’t, this is the BMW tuner DINAN’s second car ever built.
1978 BMW e21 320i converted to 333i
Approximately 35,000 miles on the original odometer. The car came with a certificate of authenticity/validity of the odometer, but the OD stopped working shortly after purchase. This car has never been a daily driver though, so current mileage estimates are probably no more than 50k. The certificate is no longer available.
3.2L Turbo charged M30 “big six” motor, non-intercooled, no BOV or DV valve.
The turbo is a t3/t4 hybrid, currently boosting 9psi with full boost achieved at 2500 rpms
I’ve been following a discussion on BimmerForums about the car and most in the know agree it’s worth $8k, even if the pictures and exact details aren’t perfect. While I agree in terms of the effort that took place to assemble, but the interior pictures are a little scary with seats that need recovering, center console with wires hanging out, and a sad and worn steering wheel. But it would likely cost at least $8k to get a similar car together, and this one is low miles with a history.
As a tuner, Dinan is so respected that their parts are sold and installed at BMW dealerships in North America — and they don’t void the warranty! So if this car represents the early history of the tuner, it could be a really cool pickup and should be a car that climbs in value with the continued success of the company.
