Porsche has won Le Mans more than any other marque, but only one of those overall race winners was actually based on a 911. That was the 1979 Porsche 935 K3, chassis number 009 00015 that was entered by brothers Don and Bill Whittington. It went on to win at the Nürburgring and Watkins Glen, and scored podium finishes at Sebring and Brands Hatch as well. In short, it's a historically significant and hugely valuable piece of motorsport history. And it was just seized by the DEA. Sorta.
