For BMW enthusiasts, the E-24 generation 6-series is one of the marque’s most beloved models, introduced in 1976 to replace the outgoing 3.0 CS and CSL. In 1983, BMW unveiled the ultimate specification of the series, the M635CSi. Specially outfitted by the “M” division with the 3.4-liter DOCH six-cylinder engine of the legendary M1, this was the ultimate high speed BMW of the decade and a performance and status icon of the 1980s.

Only 1,767 examples were brought to North America, and they were named simply “M6” and fitted with the same uprated engine, 15-inch alloy wheels, larger front air dam, front brakes and rear differential as their European counterparts, as well as a Nappa leather interior.

This car was auctioned off by RM Auctions in June of 2010 at the Town and Country Resort & Convention Center, San Diego, California.

286 bhp, 3,453 cc DOHC fuel-injected inline six-cylinder engine, five-speed manual transmission, four-wheel independent suspension, four-wheel disc brakes. Wheelbase: 103.4"
