462 horsepower Euro 1986 Dinan BMW M5

The Last Detail of Chicago has this sweet one owner M5 for sale.

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.

1978 BMW e21 320i with 3.2L Big Six Swap: Is This Really the Second Car Dinan Ever Built?

This eBay auction for a red 87 BMW 333i swap states that is the second car the Dinan ever converted! Check it out here on eBayMotors with a buy-it-now of $8k!

quote from seller’s eBayMotors listing:

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.
