Richard Rawlings and Aaron Kaufman deal in rusty gold. The proprietors of Gas Monkey Garage in Dallas buy, restore and resell forgotten, derelict American cars, everything from 1931 Model A cars to '73 Trans Ams. As "Fast N' Loud" shows, Rawlings is the mastermind, a deal-maker with an eye for relics worth their efforts, and to find them the guys search barns, fields and auctions across the U.S. Kaufman manages most restorations. He's a fabricator and self-taught mechanic, whose techniques and design skills first endeared him to Rawlings and kick-started the partnership. At the end of Season 12, that partnership ended when Kaufman exited Gas Monkey, leaving Rawlings as the series' sole star.
