Richard Rawlings, owner of the Gas Monkey Garage, and master mechanic Aaron Kaufman turn old cars into rare jewels. The two partners travel across Texas, scouring clammy barns and abandoned fields in search of relics to revamp. From refitting a 1971 Dodge Scat Pack Challenger with a 2015 engine, to installing a hydraulic system in a 1978 Cutlass, each car comes with its own challenges. And these two buddies are always in a race against the clock, trying to finish their latest transformation in time for the next auction.
