Wayne Carini chases cars for a living. Not literally, but if a vehicle were an iconic Mercedes Gullwing or a luxurious Maserati Ghibli, for instance, and Carini saw it in motion, it's a sure bet he would get himself in gear and run after it. That's how much this man loves classic cars, a passion that Velocity has captured for this series since 2008. Known as a "collector car archaeologist," Carini leads viewers into the business of locating high-end automobiles stashed in homes, garages and barns in the U.S. and abroad. When he finds a gem, Carini negotiates to buy it, then resells at auction or privately. Along the way he talks shop with respected collectors, restorers and artisans.

Car enthusiast Mike Brewer and internationally renowned car designer Ant Anstead work together to give new life to run-down, classic automobiles in order to resell at a profit. Working with a limited budget, Mike's job is to find and purchase a vehicle before presenting it to Ant, who makes the necessary repairs -- and there usually are plenty of them -- giving tips along the way about electrical and structural issues, mechanics, cosmetic touches and finishing work. Once complete, the restored car is taken for a test drive, and then Mike negotiates the purchase price with a new owner. 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.

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.
