In 1976, BMW introduced the Paul Bracq-designed E24 6-Series Coupe as a replacement for the outgoing 3.0 CS and CSL models. In 1983, BMW introduced the ultimate specification of the series, dubbed the M635CSi (The United States version was named the M6). Power was from BMW's 'M' (Motorsport) division with the 3.4-liter DOHC six-cylinder engine of the M1 supercar.
Produced between 1983 and 1988, there were just 4,088 examples of the M635CSi (or M6). The M635CSi, powered by the DOHC 24-valve six-cylinder engine, included a deep front air dam, sport suspension and limited-slip rear differential, as well as Michelin TRX tires on alloy wheels. Optional equipment included Nappa leather upholstery, power-operated front seats, rear air-conditioning unit, and a central beverage chiller.
This European-specification M6 is a two-owner car that has just over 61,500 miles. It has air conditioning, Nappa leather upholstery, and a complete tool kit and spare tire with wheel assembly.
In 2011, this vehicle was offered for sale at the RM Auction sale in Scottsdale, Arizona. It was estimated to sell for $20,000 - $25,000 and offered without reserve. As bidding came to a close, the car had been sold for the sum of $22,000, inclusive of buyer's premium.
