While the 2010 Shelby GT500 disappointingly failed to cross the block, Mustang fans were still treated to a pretty good show when a 2009 FR500CJ Cobra Jet roared up on stage. Behind the wheel was none other than legendary drag racer John Force, who personally testified to the car's capability on the dragstrip. This particular car is the prototype and the very first one built with the FR500CJXX1 serial number. We didn't expect the FR500CJ to fetch as much money as the first production Camaro, but we were thoroughly surprised when it trounced its fellow pony car with a final bid of $375,000, or $412,500 after auction fees. Follow the jump for a full description of the car, and check out the high-res gallery below.
