1972 Funco SS1

Ivan "Ironman" Stewart has retired, and the legendary off-road racer didn't play around when it came to getting out of the game. This weekend, 650 items from his 37-year racing career are being auctioned off, including the entire Pro Truck business he's been running for the last ten years.

Items up for bid range from pieces of racing history like the restored Funco SS1 buggy (above) that ran the 1976 Baja 1000, to racing miscellany like antique fire sprinklers and five antique folding seats. Not bad if you want to sprinkle your souvenir room with a little bit of Stewart's dust.
