Shelby GT500 Super Snake – $1.3 Million
This unique Shelby GT500 was meant to be a rolling laboratory to showcase the possibilities of the Mustang platform, as well as for testing Goodyear’s “Thunderbolt” tire line. It had a Le Mans-winning GT 40 race engine, special transmission, suspension, and tires. But most interesting of all is that they only build one of them. Although there were plans for a limited production run, the proposed price was over $8,000, which was an enormous sum in the late â60s. Recently, this sole example sold for $1.3 million.
