Shelby GT 500 Super Snake
This unique Shelby GT500 was produced as a rolling laboratory to showcase the possibilities of the Mustang platform. It had a Le Mans-winning GT 40 race engine and was produced in one example (via Supercars).
There were plans for a limited production run, but the proposed price was over $8,000, an enormous sum in the late ’60s. It’s too bad since it was capable of 170 mph, unheard of in the late ’60s.
