Ford Mustang Shelby GT500 Convertible

Carroll Shelby, the renegade Texan who built and sold the legendary 289 and 427 Cobras and was responsible for some of Ford’s greatest sports car racing victories, also applied his magic to Ford’s hot new Mustang – a vehicle that he initially derided as a mere “secretary’s car.” However, the resultant GT350 was a thinly disguised race car that proved quite successful in competition but offered few creature comforts. It soon became apparent that these street cars needed to be more user friendly, and so for 1966, a host of revisions softened its hard edges. Despite calls for added comfort, the Shelby formula still had to be fast. So, as the new 1967 Mustang body shell had been designed to accept Ford’s 390 cubic inch big block engine, Carroll Shelby unsurprisingly took the next step by shoehorning the Interceptor 428 into the pony car’s engine bay. Conservatively rated at 355 horsepower, output was closer to 400 with 420 pound-feet of tire-scorching torque!

Although this powerplant was very similar to Ford’s standard offerings and would continue to power the GT500 through 1970, stylists ensured that the cars retained their unique Shelby identities. Their rarity has ensured their position among the top echelon of collector cars today – just 335 GT500 convertibles were built in 1970.

This car was auctioned off by RM Auctions in January of 2010 at the Arizona Biltmore Resort & Spa, Phoenix, Arizona and in November of 2010 at the Robson Estate, Gainesville, Georgia.
