When it comes to high-performance cars, the phrase win on Sunday, sell on Monday is still, very much, true. But it was in the 1960s when those words were most notably put into action. The Shelby Cobra is one of the most legendary cars from the 1960s. It was also very successful in motorsports and Chevrolet didnt like that. So, they turned to an old Chevy associate Bill Thomas. He, in turn, came with a car even crazier than the Cobra the 1963 Cheetah.
