With just 75 built between 1959 and 1963, the Aston Martin DB4 GT is a rare breed. Of those, a mere six are the coveted lightweight models that cut weight by using aluminum components (instead of steel) and delete items like the radio, speakers, and heater. It's not very often that one comes up for sale, but this January, RM Auctions will be offering a pristine example at their sale in Scottsdale.

The car going up for auction is chassis #0175/L, the last DB4 GT Lightweight built. It underwent a total restoration in the mid-Nineties where it received upgrades like Dunlop racing tires, Dayton wire wheels, and a four-point roll bar. The car wasn't competitively raced in the Sixties, but several owners have competed with the car in various vintage races at tracks like Lime Rock Park and Laguna Seca.

Sound like your kind of car? RM estimates you'll need anywhere from $950,000-$1,000,000 to take this ruby beauty home.
