9. 1966 Shelby Cobra Roadster – $1,000,000
The 1966 Shelby Cobra Roadster is one of the most beautiful muscle cars ever sold at auction. This one sold for a cool $1 million dollars at an auto auction in 2014. While this vehicle was clean before a restoration that it underwent in 1991, it came out in immaculate condition and is considered one of the finest Carroll Shelby Cobras in the world today.
