Built as an "idea car" with a fiberglass roadster body, the Plymouth Belmont rolled on a 114-inch wheelbase and delivered power courtesy of a 150-horsepower V8 from the Dodge division. Just 49 inches tall, this sleek two-seater was developed in 1953 for debut at the Chicago Auto Show.  

Three years later it was featured in the Tony Curtis movie, Mister Corey — and viewers had no idea the car had made production status. If the Belmont had been produced, it would have been a direct competitor to the Corvette and Thunderbird.
