As part of the Mecum auction at Nashville Superspeedway, RFK Racing put forward a collection of performance vehicles and motorsports artifacts to be auctioned off. Among the items was the iconic No. 16 National Guard-sponsored Ford Taurus (chassis RK-195) that Biffle drove throughout the 2004 NASCAR Cup season, and into 2005. The car includes a Roush-built 358 cubic-inch (5.8L) Ford V-8 engine. Biffle won two of his 19 career Cup Series victories during the 2004 season, but the RK-195's best result was a third at Atlanta in early 2005. Proceeds from the sale of the car will benfit the Biffle Family Legacy Impact Fund. Greg tragically died alongside wife Cristina, his daughter Emma, and their son Ryder in a December 18 plane crash last year, which also claimed the lives of Craig Wadsworth, Dennis Dutton, and his son Jack Dutton. "Thank you to Jack Roush and everyone at Roush for including Greg’s car and pledging the proceeds to the Biffle Family Legacy Impact Fund," said Jordyn Biffle (Greg's niece) in a Facebook post. "We’re grateful for their support and proud to see this car continue to make a difference.
