A classic Ford Mustang is a wonderful item to put in anyones garage. Make it a Shelby GT500, however, and you're owning an excellent example of a rare piece of motoring history. What could you do to make it even more rare? Find an GT500 that was owned by the man whose name is on the back, Carroll Shelby.

Now's your chance to do just that because Mecum is set to auction off an ultra-rare pony car owned by the man himself.

The car in question is a 1969 Shelby GT500. According to Mustangs Daily, the Grabber Yellow paint it wears makes it just one of eighteen built in that exterior shade. Additionally, it's just one of three to be equipped with a 3.50 Traction-Lok rear axle. The current owner purchased the car from Mr. Shelby and then proceeded to restore it over a ten-year period.

Under the hood is a 428 Cobra Jet V-8 engine, and it's paired with a four-speed manual gearbox. With just 4,317 miles on its odometer, the Shelby ownership history, and the rare color and rear axle, this should be one rather expensive muscle machine. It will cross the Mecum block at the Monterey auction in August. Our pre-auction guess? This should fetch low-to-mid six figures.
