S.A. Williams built a miniature car for his son Bobbi that proved to be so popular, William's friends encouraged him to market a full-size model. There was quite a market for automobiles after World War II, so Williams hired consultants and designers to produce a $500 car that would travel 50 miles on a gallon of gas. The Bobbi-Kar's odd look was the result of form following function. Its component design meant it could be taken apart and reassembled as needed.
Production models were to be equipped with lightweight plastic body panels in various colors mounted to an inner structural body for easy repair. The one-piece rear deck and fender assembly were hinged at the back and could be raised, unlatched, and removed.
Releasing latches located above the windshield and at the rear deck line permitted the easy removal of the hardtop, which could be stowed away in the package compartment under the flat hood. Inside, the dashboard was covered with thick foam rubber padding and upholstered in leather—a less expensive alternative to applying expensive chrome trim, graining, or decals.
Since you've never heard of the Bobbi-Kar, you might assume that the company went out of business because the car was ugly. That's not what happened at all. Read the surprising story of the Bobbi-Kar at The Old Motor. -via Everlasting Blort
