The prototype for the 1966 Shelby Mustang – the year before the one Nic Cage drove in Gone in 60 Seconds – is on the auction block in Monterey, CA for the first time in 40 years, and it’s looking ace. In fact, it was not only used at the prototype for the ’67 Stang, but was driven by Ford factory stylist Charles McHose. Now, you can buy it at auction next month. 

"Early Shelby GT350s are one of the hottest tickets in the muscle car market today and cars with a verified Prototype status like 5S319 typically command a premium price," says Frank Mecum of Mecum Auctions, which will feature the car on live television on Mecum Auctions’ "Muscle Cars and More" on Discovery’s HD Theater.

McHose’s biggest influence on the prototype is the unique rear spoiler that would become the most prominent distinguishing feature of the later model Shelby GT cars. It may have also been the first time ever that a rear spoiler was incorporated into the design of an American production vehicle.  As a prototype, 5S319 was fitted with functional rear brake side scoops, side quarter windows, modified Shelby side stripes, under-ride traction bars and a trunk lid with spoiler. All of these new features were implemented on the ’66 models except for the rear spoiler that was introduced on the ’67 model.

The 5S319 is also fitted with a very rare 1966 Ford AM 8-Track radio, 1966 rear shelf (carpeted), 1967 Shelby wood steering wheel and a mid 60s Shelby Cobra medallion on the glove box door.

An original California “Black plate” car, which means it had a production year between ’63 and ’69, and has been in the state of California since it was built. It is listed in the Shelby Registry and is supported by over 30 years of documentation, including a period photograph of Charles McHose posing with the car in the 60’s.
