Hollywood car builder/customizer George Barris made two replica 1914 Bearcats for the series. A period TV Guide article said they cost $25,000 for the pair, this at a time when a new Corvette was about $5,000. The cars were full scale metal bodied replicas mounted on custom frames and powered by Ford engines and transmissions (out of (then) late model pickups. For safety they featured four wheel brakes, which were not on a genuine Bearcat. The brass radiator is interchangeable with a genuine Stutz unit.
