Designed and built by George Barris.

The Koach was made from 3 Model T bodies and is 18 feet long. The 133" frame was made by hand.

It has a four speed manual transmission and a power rear end. The brass radiator and fenders were hand formed. In 1964, the cost to build the first one was $18,000.00. It had "blood red" velvet interior. It took 500 hours to hand form the ornate rolled steel scrollwork. It had Gloss Black Pearl paint. The front end had a dropped axle, split radius rods and T springs. The studio gave George Barris 21 days to complete the car. Powered by a 289 Ford Cobra engine from a 1966 Mustang GT. Built with Jahns high compression pistons, ten chrome plated Stromberg carburators, an Isky cam, and had a set of Bobby Barr racing headers.
