Here at GCFSB, we feature a lot of cars. Since I started writing for this site, I’ve composed some 1,773 articles, a fair amount of which cover more than one car. So it would be easy to forget that you’d already seen a car. That would especially be the case if a fair amount of time had passed since you last saw it and it was a relatively plain-jane looking model.
Enter this 1989 535i in Cirrus Blue Metallic. Outside of Hartge wheels, it’s pretty unassuming. That is, except for the “Dinan” badge on the left side of the trunk.
It’s that Dinan badge which unlocks a world of performance that otherwise is the domain of M models, and this sleeper package with low reported miles seems to be a pretty compelling alternative. Immediately, I recognized this car but knew it had been a bit since I last saw it. Since it was originally featured in March of 2014, very little has changed – the seller utilized the same photos and much of the same description from the original ad, disappointingly. He reports about 500 more miles in two and a half years, and unsurprisingly the price has dropped little. The auction is no reserve with an $11,250 starting bid – only about $750 less than the original ask. As the market on E34s really hasn’t improved greatly since then outside of some exceptional M5s, I’d wager this automatic 535i – even with the Dinan provenance – will have trouble this time around, too.

The below post originally appeared on our site March 11, 2014:
When I was a younger lad, I diligently followed the car magazines. It was in the late 80s that a small California-based firm named after its creator, Steve Dinan, started gaining the notice of the car magazines. The reason why was simply; just as Reeves Callaway had done on the East Coast, Steve Dinan was taking already potent cars and turbocharging them in the Golden State. In this case, it was E28 and E24 M5 and M6s that were getting forced induction, and the results were unreal. At the time, having 400 horsepower put you into the likes of Ferrari, Lamborghini, and a few other exotics. Dinan didn’t rest on those laurels though, and since has become a defacto factory tuner in a similar vein to AMG, though they remain independent. That’s a testament to the quality and reliability of their work. What they produce are improved versions of already fast cars, and today’s 1989 535 is a great example. The E34 was a solid performer in its day, but with a turbo and 300 wheel horsepower, it’s an undercover M5 assassin:
Engine: 3.5 liter turbocharged inline-6
Transmission: 4-speed automatic
Mileage: 77,000 mi
A great piece of BMW history. From what I’ve gathered this is 1 of 15 and 5 of those were automatic. 77xxx miles.
Known as the “Delaware” car it was shipped to the Dinan shop in California and had an intercooled turbo, upgraded suspension, brakes, upgraded Dinan exhaust, Dinan 3 vdo gauge(oil temp, boost/vac, volt) panel, Dinan turbotronic computers, Dinan floor mats, safegaurd knock detector system all installed and was shipped back to DE. The wheels are Hartge Type A wrapped in Riken radials. The wheels were reconditioned, and the tires are less than 2,000 miles old.
The car was given to a previous owner by his wealthy developer boss. After many years it went into the same performance shop it was maintained at in DE for a leaking head gasket and leaking tranny. Once given the estimate the owner couldn’t afford to repair it and sold it to the owner of the shop. The shop owner had the HG repaired complete with 3 angle valve job, rebuilt the tranny and stored it driving it on occasion. When the transmission was rebuilt (<2,000 miles ago) the converter was loosened (3,000 rpm stall) and a shift kit was installed. During this time the speedo was replaced. There is a validation sticker on the door. In his care the engine had been completely gone over including new belts, upgrading the injectors and a new fuel regulator was installed. It’s been adult owned, stored in garage all its life and well maintained. It has had one repaint. IMO the paint is very good. No clear coat cracks but not perfect as there are some small dings here and there. There was an old cell phone mounted in the car and a couple small holes remain from the mounting bracket in the passenger foot well. That said this may be the cleanest of all of these on the road. I've had dozens of internet tire kickers and numerous no shows over the past so don't waste our time...yeah its fast. -Turbo just rebuilt -Ac recharged -Pa inspection Will work with shipping you set up. Old Description
Vin: WBAHD2313K2091373. Clean title in hand.
Rare 535i Dinan Turbo. Not a kit put on by some mechanic, she’s the real deal. I gathered 1 of 15 built in Steve Dinan’s CA shop, 5 were automatic. Originally from Delaware it was shipped to CA and had an intercooled turbo, upgraded suspension, brakes, upgraded Dinan exhaust, Dinan 3 vdo gauge(oil temp, boost/vac, volt) panel, Dinan turbotronic computers, Dinan floor mats, safegaurd knock detector system all installed and was shipped back East. The Hartge Type A wheels were reconditioned, and the tires are less than 2,000 miles old.
The car was previously owned by a performance shop owner. It has a recently rebuilt head (complete with 3 angle valve job) and rebuilt transmission (both <2,000 miles ago). When the trans was rebuilt the converter was loosened (3,000 rpm stall) and a shift kit was installed (common in automatic hot rods). Have receipts. In his care the engine had been completely gone over including upgrading the injectors and install of a new fuel pressure regulator. All belts replaced. I have receipt for the trans and head work. Clean inside and out. It's been stored in garage all its life, well maintained and it shows. It has had one repaint. There is nick or two in the rear bumper, one but the driver door handle and two or three small dimples in the body. The turbo pushes ~12lbs of boost and pulls very hard with little lag. Even at 24 she remains world class fast. From the articles ~300whp feels right. Driven out of boost and she's pretty economical, ~25 mpg hwy. Recent: -PA Inspection -A/C recharged -New trunk struts -New ignition switch -New rear passenger door cable -New rear control arm dogbones -New front rotors -Oil/filter change It is what it is: -The CEL will randomly come on with your foot off the gas as the air/fuel ratios battle it out between the main computer and turbo computers installed Dinan. It clears as you drive. Code reads lean at idle. In speaking with Dinan about this it was said "it is what it is". My mechanic and Dinan believe it's fine the way it is but it could be tuned out. I just don't have the time and its fine the way it is. -The odometer was replaced at ~54k. There is a validation sticker on the door. The car was recently driven on a 700 mile journey through the Green and Adirondack Mountains without flaw. A new baby has changed priorities. Its more of a cruise missile than a twisty killer but regardless its a blast to drive. My wife and I rarely listen to music preferring the sweet sound of the turbo spooling. Its a wonderful car in super shape and I hope it goes to someone who will appreciate it. It will come with a framed original ad where I'm 99% sure it's the car in the picture. Will work with shipping. I can put you in touch with my mechanic. I'd also be willing to take her to renowned VAC Motorsports in Philly for a PPI at your expense. Asking 12,000. Reasonable offers considered. May trade for convertible and cash or car with similar value. Rob 4eight4-9four9-4six7six Pictures: http://www.flickr.com/photos/93289116@N06/
As a standalone, it’s an impressive condition E34 with lower miles. Add some Hartge wheels for improved looks without going over the top, and that’s another win. In fact, aside from the wheels and discrete “Dinan” badge on the back, this car is a true sleeper. It’s also an automatic, which may turn off some enthusiasts but with ample torque and turbo power delivery, the automatic isn’t necessarily so bad. The price is probably lower than you’d expect for a one of fifteen rarity, but I think considering what it is it’s priced quite realistically and presented well. It will be sure to offer the next owner a lot of smiles per dollar spent and differentiates you just a bit from the typical E34s that people seek – the M5 and the 540i M-sport. Want to take a road that’s less traveled? It’s a quick one, for sure.
Thanks to our reader John for spotting this neat and rare ride!
