This car is one of only 12 of its kind that are known to survive. Powered by a supercharged 8-cylinder engine, this was, one of the most advanced sports cars one could buy in its day. The beautiful body, crafted by the Italian coachwork company Touring, was built from super-thin steel tubes covered by a lightweight aluminum skin.
