1967 Shelby Super Snake – 1 Made
This unique Shelby GT500 was produced as 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. Only one ever left the factory (via Supercars).

There were plans for a limited production run, but the proposed price was over $8000, which was an enormous sum in the late ’60s. That was too bad since the Super Snake was capable of 170 mph top speed, unheard of in the late ’60s. It could put the Mustang as the world’s fastest muscle car. The car sold twice in recent years and had set up a couple of auction records. The last one was $2.2 million.
