George Barris' shop built both the "Munster Koach" and "Drag-U-La" used in that short clip.
Barris is a living legend. Born in Chicago to Greek immigrant parents, he and his brother started customizing cars in the 1940's. They began doing custom work for Hollywood in the 1950's and became best known for creating the Batmobile from a unique Lincoln Futura. Barris kept the Batmobile until quite recently, selling it for $4,260,000.00. That seems like quite a profit, but consider that the original Lincoln Futura was never commercialized and cost around $2,200,000.00 to produce in 2015 dollars. So George roughly doubled the value.
