This is the 1992 Mustang Mach III Concept, probably the most familiar concept Mustang. This two-seater roadster was created to spark interest before the release of the 1994 Mustang. It had a supercharged 4.6L 4v V-8 with 450-horsepower, 440 ft-lbs. of torque, a top speed of 180 mph, a 0-60 time of 4.5 seconds, and a 1000-watt stereo system.

The final remaining model--the green one pictured below--sold at Christie's Auction in 2002 for $491,500.
