http://www.autoblog.com/2009/12/18/1995-ford-gt90-concept-going-up-for-auction/ If Ford first introduced the GT90 Concept at the 2010 Detroit Auto Show next month, we would probably consider it one of the coolest cars on the show floor. Incredibly, Ford unveiled the GT90 nearly 15 years ago. Even by today's standards it is a supercar of supercars. The quad-turbocharged 6.0-liter V12 puts out an estimated 720 horsepower, the body is constructed completely of carbon fiber and top speed is somewhere in the 250 mph range. The only hints that it's not a modern supercar are the all-blue interior and wheels that are decidedly not from this decade. So why are we talking about the GT90 Concept now? RM Auctions has just announced that it will be offering the car at its Arizona sale. That's right, this is your chance to own one of the coolest concept vehicles of all time. This is the first time that the GT90 Concept has ever been publicly for sale at auction, and RM claims that it is in "excellent running condition, having been properly stored and maintained over the year." No estimated price is given, but we're guessing it will take a significant chunk of change to take the car home.
