When it comes to special editions, it doesn’t get any rarer than one of one. In an auction to support the Henry Ford Health System, a unique 2013 Ford Shelby GT500, custom designed by Ford stylist Melvin Betancourt, will be sold to the highest bidder.

The charity car features a white exterior with white accent striping and white 20-inch wheels. Inside, the Recaro seats are wrapped in (you guessed it) white leather, stitched with contrasting black thread. The design of the car was done as a “thank you” by Betancourt, himself a former patient of the Henry Ford Health System.

No changes were made to the Shelby GT500’s drivetrain, but we’re OK with that. After all, do you really need any more than 662 horsepower and 631 pound feet of torque?

The car will be sold during the Get Your Hear Racing Pit Party on September 22, at Ford’s Dearborn Development Center, with all proceeds going to benefit the Edith and Benson Ford Heart & Vascular Institute at Henry Ford Health System.

Last year’s auction car, a one-of-one 2012 Boss 302 sprayed up in School Bus Yellow Parnelli Jones livery, sold for a respectable $300,000, which should give you an idea of how much you’ll need to spend to add this particular 2013 Shelby GT500 to your garage.

Specific auction details have yet to be posted, but you’ll find the auction webpage here.
