When this Alpina B7 S rolled off the assembly line in 1982, it was the fastest sedan you could buy — and one of the fastest cars made. Starting with the BMW E24 6 series, Alpina added a turbocharger to the 3.5-liter inline-six, making 330 horsepower — enough to easily outrun the Ferrari 308 GTB. This particular Alpina was exported to Nicolle Japan, Alpina's official dealer for the country, and has had only three owners since new and now shows only 73,000 miles on the odometer. The car has extensive documentation showing servicing and a recent engine bay restoration, including being fine-tuned by an expert. Wearing its original Sapphire Blue paint and interior scheme, this Alpina is the perfect complement to any '80s sportscar collection.
