    1967 Shelby Mustang GT 500Any Mustang massaged by the Shelby American skunk works can be regarded as rare, but this 1967 ragtop is arguably the rarest of them all. Unique, in fact- the only 1967 Shelby GT convertible built.

    The car was one of three 1967 Mustangs delivered to the Shelby shops late in the summer of 1966. Besides the convertible there was a fastback and a formal coupe, each with a Ford 428 cubic-inch police interceptor V8 under its hood.

    Like Shelby's GT350, the GT500 was a limited edition, higher performance version of the standard Mustang. But unlike the competition-oriented GT 350, the 500 included civilizing elements for everyday use: air conditioning, a radio, power steering, and power brakes.

    Ford rated its interceptor V8 at 345 horsepower. Shelby adapted the cast aluminum intake manifold from Ford's 427 cubic-inch V8, mounting a pair of 4-barrel Holley carburetors for enhanced nourishment. So equipped, the 428 was pegged at 355 horsepower, a conservative rating undoubtedly put forth to placate insurance companies. Carroll Shelby listed the convertible as a 1968 prototype, for use in brochure photography, as well as driving by Shelby American staffers, including Shelby himself.

    The convertible was restored by Jeff Yergovich of R&A motorsports in Lee's Summit, Missouri. The work was completed in November of 2011.

    Shelby originally listed the convertible's value at $4,249.76, the most expensive Mustang of its day.
