The BMW 635 Coupe was in continuous production from 1973 to 1989 and is one of the most iconic BMWs ever built.

In 1987 and again for the 1988 and 1989 model years, BMW upgraded the car to an M-series by installing a variation of the by then famous Ml racing engine which dramatically increased the available horsepower and also made it the fastest production vehicle in the world with a top speed of 158 mph, but also made the cars extremely expensive. In total, 1632 were built for the American market over that three-year production run, roughly 540 per year.

Before Jim acquired this 1988 M6, it was owned by a prominent collector who decided to improve on the existing technology of what was then a 20 year old car: he had Metric Mechanics of Richland, Missouri (a nationally recognized leader in BMW customization) rebuild the engine and as a result increased the horsepower from 258 to 360 while retaining its 5 speed Getrag manual transmission. In addition, he had Metric add a Dinan Engineering Stage III suspension, a Stebro of Canada stainless cat-back exhaust system and BBS RS wheels.

Jim’s car under prior ownership received a slew of awards at BMW judged events in the Western United States and as the photos reflect, is cosmetically flawless.
