Just two COPO Camaro Convertibles exist in the world. One of them is proudly on display at the GM Heritage Center where it'll remain for the rest of its days. The second was just sold on the weekend at the Barrett-Jackson auction in Scottsdale, Arizona, for a cool $400,000. First shown at the 2012 SEMA show in Las Vegas, the COPO Camaro Convertible is powered by a 327-cu V8 and a 4.0-liter supercharger that produces a combined 550 horsepower and is mated to a three-speed Powerglide slushbox.

Consider this the perfect combination for a fast quarter-mile drag race, only with the top down. All proceeds from the sale will go directly to the American Heart Association. The question remaining, however, is whether its new owner will race it or keep it garaged because of its exclusivity.
