First up is the Ford Shelby GR-1 Concept, first introduced to the public at Pebble Beach in 2004. Built to celebrate the 40th anniversary of the legendary Shelby Daytona Coupe, the car features a silver paint scheme with blue stripes and 12-spoke 19-inch wheels. Unfortunately, the car is not a running example, unlike the polished aluminum version that debuted at the Detroit Auto Show a few months later.
Next up is the Ford Thunderbird Sports Roadster Concept that was first shown at the 2001 Detroit Auto Show. A precursor to the Ford Thunderbird production car, the Sports Roadster is set apart by a molded fiberglass tonneau that's neatly integrated into the rear decklid.
As is custom for Ford when auctioning off cars, proceeds from the sale will be donated to charity. The sale of the two concept cars, each valued between $125,000 and $200,000, will benefit the Juvenile Diabetes Research Foundation (JDRF).
