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.

It takes a lot of nuts and bolts, so to speak, to challenge Richard Rawlings and his crew at Dallas hot rod shop Gas Monkey Garage. But that's what mechanics Tom Smith and Jordan Butler are fixin' to do by opening a rival shop with fellow car pros Thomas Weeks and Scot McMillan. The venture, Fired Up Garage, is their chance to go toe-to-toe with powerful Gas Monkey -- featured in Discovery's hit series "Fast N' Loud" -- and prove that they have what it takes to run a car business. Smith and Butler have extra motivation, too: They worked at Gas Monkey before a series of mishaps forced Rawlings to fire them.

Now, Rawlings is ready to pass along that knowledge to help struggling garages in desperate need of transformation. Joined by project manager Russell J. Holmes and garage designer Chris Stephens, Richard takes on seemingly impossible challenges -- dealing with out-of-touch owners, lazy employees, bad workflow and significant construction issues -- and uses his entrepreneurial savvy, deep knowledge of the auto industry, and multifaceted marketing skills to produce profitable businesses. Russell gets the rehabs done on time and on budget, while Chris implements Richard's vision for the shop.

The series, a British import, began airing on Discovery Channel in the U.K. in 2003. Its first 13 seasons featured master mechanic Edd China as Brewer's sidekick.
