21. 1956 Austin-Healey 100
1956 marked the last year of production for Donald Healy’s in-house sports car. The 100 designation was simply because the car could reach 100 miles per hour. Its successor, the 3000, was named for its 3000 cc engine displacement. The 1956 version, the 100S, was primarily built for racing, and only 50 were produced, along with five more “work” vehicles. The bumpers and convertible top were eliminated and the windscreen made out of plastic to drop 200 pounds off the car’s weight.
