12. Chevrolet Corvette Nomad
Back in the mid-’50s, GM held the Motorama traveling car show. It features some crazy concepts, future cars, and promotional materials. Those were the glory days of the American concept car trend. Each year, manufacturers competed with different cars that later became car styling and pop culture icons. In 1954, Chevrolet presented the Corvette Nomad. They named it the Waldorf Nomad since it first appeared at the Waldorf Astoria Hotel. It was practically a Corvette station wagon, but the design proved to be influential. Chevrolet presented the Nomad as a three-door station wagon.

It became part of the mainline Chevrolet model lineup just a year later. Also, the Corvette Nomad was one of the most popular concept cars from the Motorama period. After their short lives on the show circuit around America, most concept cars went to the crusher, but some managed to survive. This is where the Corvette Nomad case gets strange. Since it was a fully functional vehicle, the chances are they sold it, possibly to an employee or dealer. There are no records to show they crushed this car, but there are no records to prove someone bought it, either. It vanished in the mid-1950s and Corvette fans have been searching for it ever since.
