The Winton Flyer was not a real automobile. It was created from scratch for this movie by Kenneth Howard, aka Von Dutch. The car was designed to resemble a typical vehicle from 1904, but built to withstand the rigors of filming. Steve McQueen called the car "the real star of the picture", and took possession of it after filming ended. It remained in his collection until his death in 1980. It can be seen in the Peterson Automotive Museum In Los Angeles.
