1967 Shelby Mustang GT500 Super Snake – $1,300,000

This is the most highly sought after Mustang there is. Why? It’s the only one. It was originally built as a test vehicle for Goodyear before being fitted with a lightweight 427 race engine and given the name ‘Super Snake’. The plan was to sell a limited number of them to the public but because the estimated cost was so high, no more were ever built.
