1. Cadillac Le Mans
In 1953, Cadillac presented the Le Mans Concept, naming it after the legendary French racing track they raced on in the late ‘40s and early ‘50s. They designed this concept car as a styling exercise. In fact, the design of the car, including its lines and details including its legendary four headlights are still visible on future Cadillac models.
They conceived the car as a roadster with an unusual three-seat configuration. Interestingly, they made it out of fiberglass, just like the first Corvette. The legendary mysteries of famous lost cars still intrigue many people and car historians today. If you ever see any of these treasures, be sure to take a picture before it disappears again.
