Former NASCAR driver Greg Biffle surprised a fan with a new car and $1,200, according to a video he uploaded via Instagram just five days before his death at age 55. "🎉🎉We have called and spoken to the winner of the Corvette + $1200 congrats to Brandon P from Alabama!," he wrote in the caption on Saturday, December 13. "Thanks so much for sharing the videos this Biffmas can't wait for next year !!" In the accompanying video, Biffle is parked at a gas station, where he takes out his phone and calls the lucky winner. "Hey man, how's it going?" he asks when the winner answers.
