Shelby GT500 Super Snake – $1.3 million
This unique Shelby GT500 was produced as a rolling laboratory to showcase the possibilities of the Mustang platform and test Goodyear’s “Thunderbolt” tire line. It had a Le Mans-winning GT 40 race engine, extraordinary transmission, suspension, and tires, and it was produced in one example. There were plans for a limited production run, but the proposed price was over $8000, which was an enormous sum in the late ’60s. Recently, this sole example was sold for $1.3 million.
