1988 BMW M6

For sale in our Dallas/Fort Worth showroom is this classic 1988 BMW M6. It is powered by a 3.5L/256hp inline-six engine that is mated to a 5-speed manual transmission. This is a beautiful example of a rare BMW M6. Values on M6’s are constantly increasing from year to year. Currently they are still affordable but who knows how long before they become a six-figure collectible car.

Engine sizes gradually increased to 3.2-liters then 3.5-liters, but the 6-Series really hit a bullseye with the M635CSi, which appeared at Frankfurt in 1983. Apart from the 282-bhp M1 engine, it had a limited-slip differential and the “track link” suspension from the big 7-Series sedans, which was designed to reduce oversteer. ABS brakes arrived at the same time, along with a five-speed manual gearbox or a four-speed ZF automatic.

Badged simply as the BMW M6, the 635CSi finally reach the U.S. in 1987, lavishly equipped with twin air-conditioners (and a beverage chiller in the rear), hand-stitched Napa leather interior with eight-way power front seats, and an eight-speaker sound system. Distinctive M6 details included M badges front and rear, a larger front air dam and rear spoiler, and matching color side mirrors. The cars were fitted with new ellipsoid headlights, which directed a more precise beam onto the road.

The M6 could manage 0-60 mph in 6.1 seconds, a quarter mile in 14.7 seconds and cruised easily at 140 mph. It retailed for $55,950. BMW electronically limited even its sportiest models to 155 mph in the U.S., but Rug Cunninham BMW ran a de-limited M6 in the 1989 La Carrera Pan American race in Mexico and reported a top speed of 176 mph. In all 5,859 M 635 CSi cars were built between 1983 and 1989, with 1,787 of those being the slightly detuned U.S. model BMW M6. The Original Wheels and Exhaust are available with this vehicle.
