1985 BMW M635CSi

1985 BMW M6 ShadowLine

1985 M635CSi (Euro): WBAEE310X01051648 Diamond Shwartz/Black leather/alcantara, M88/3 engine, 5-speed, 92k miles. Complete body/powertrain/drivetrain/suspension/interior overhaul using majority OEM parts. Non-std: F&R Tower Struts, Coil overs with Koni shocks, Type 32 wheels, Kenwood ICE system. includes many extras.
The iconic European spec BMW M635CSi is lighter, faster, more powerful and arguably better looking than the M6 that eventually made its way to the US. With only 1,767 M6 models imported between 1987 – 89 into the US making the M635CSi even rarer and more desirable. This is the ultimate sports version of the shark nosed grand tourer designed to cruise the autobahns all day at speeds up to 158mph. Imported as new in 1985 this example has undergone a full body strip down and diligent rebuild at 87k miles. The intention behind the rebuild was not to create a garage-queen but to get the car back to mechanical perfection and trustworthy enough to use as a daily driver or a long-distance reliable GT car. Just some of the items covered during the rebuild…
