Here we have a 1985 BMW Alpina B7 Turbo. There are only 236 examples of this rare car in the world, and only 4 of those found their way to North America. It features a 3.5 liter inline-6 with 300-330 horsepower, which is adjustable via a turbo boost control knob. Other upgrades include lighter piston heads and modified cylinder heads, tuned exhaust manifold headers, a K27 turbo, and reprogrammed engine electronics. Seen at the 2010 Hemmings Sports and Exotics show at Saratoga, New York.
