Great news for sports cars collectors, the one-off 2005 Ford Shelby GR-1 concept car will be up for auction at RM Auctions. The car features a mixed exterior design based from both Ford GT and the 1964 Shelby Daytona coupe. However, the GR-1 has no juicer under its hood, not even a drive-train or interiors. So this concept car will not satisfy buyers looking to drive it, but only those who have the collector’s heart. The proceeds will go to the Juvenile Diabetes Research Foundation. Auction date will be on August 19, 2011. $150,000+.
