1954 Dodge Storm Z250 ZederDel Stewart

From the Museum Plaque: The Storm Z250 was developed by Chrysler Engineer Fred Zeder to evaluate the feasability of capturing a portion of the growing American sports car market. Built on a rigid tube-frame chassis, it was intended to be a dual purpose sports / racing car. When race, the comfortable [pictured] touring body could be removed by unscrewing four bolts and replaced by ultra light 150 pound fiberglass body. The Storm did not reach production because high production costs would have made it too expensive to sell in profitable quantities. 

Another chance at a great car lost to pesky issues of, you know, keeping the doors open.
