The BMW 6-Series coupe combines world-class performance with stunning elegance.  Paul Bracq was tasked with re-thinking BMW’s top-line car and the result was a squarer, more aggressive “shark-nosed” coupe, which would be built in various forms to 1989, culminating in the blisteringly fast M 635 CSi, which used the 24-valve M88 motor from the M1 and could hit 158 mph in European tune. 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 Nappa leather interior with eight-way power front seats, and an eight-speaker sound system. 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.
