The Lamborghini Miura is considered by many to be the first supercar. Jay Leno owns two: A 1967 Miura, and this '69 Miura P400S—the faster, more luxurious (the S boasted power windows) version. Only 140 P400S models were made between 1968 and 1971, with one of them going to Frank Sinatra. The V12-powered machine was fast, gorgeous, and showed the way for future supercars until it was replaced by the Countach. It's only right we give it the top spot on this list.
