One of my favorite muscle car concepts will be sold up on auction in the $250k - $350k range. The concept car, 2004 Ford Mustang GTR concept. The car is very cool looking. I love the split head lights, the big spoiler, custom hood, and mesh grille. The Mustang GTR was built to tribute 30 years of Mustang performance, but also give a look into future Ford performance. I for sure would love to put a bid in for the concept car, but $200+ is way too much money.
