A last-minute problem arises with the turbo-charged EcoBoost '72 Ford Pantera Aaron is building for the new Barrett-Jackson auction out on the east coast.

Aaron tasks the Monkeys with building a '55 Chevy that Richard plans to sell with around a million dollars' worth of other cars at a Barrett-Jackson auction.

Richard buys Aaron a 1942 Harley-Davidson WLA '45. The aim is to rebuild the bike to its original era in order to participate in a vintage race in New Jersey.

After a number of tough builds, Richard does something nice for Aaron and the Monkeys, buying them a '67 Camaro mounted on a K5 chassis. Will it lift their spirits?

With the aftermarket parts available for G-body cars, Aaron needs a fast build and bets Richard he can finish a 1980 El Camino in three weeks - not four.

Aaron bets Richard that the Monkeys can finish a 1980 El Camino a week ahead of schedule. But last-minute problems threaten to push them past the deadline.

As Richard plans to gamble selling a million dollars' worth of cars at Barrett-Jackson, last-minute problems with their '55 Chevy threaten him from taking it to auction.

With Aaron set to take off soon for a long-deserved vacation, he and Richard get the Monkeys started on giving the "proper" treatment to a '65 Volkswagen Beetle.

With Aaron on vacation, Richard gets the Monkeys to give the Gas Monkey treatment to the first car he owned back in high school, a vomit green '74 Mercury Comet.

Aaron has shock news - just as Richard agrees to a drag strip showdown with Street Outlaws' Big Chief, so the crew must build the race car.

Aaron toils to finish his BMW alone as race day approaches, and Richard faces disaster with the Challenger on its final test run.

After building and selling more cars than they can count, Richard and Aaron hit the beach for a much-needed break so they can finally answer some of the questions and comments their fans have sent in over the years.

It's a new start at the garage. Richard puts the Monkeys in charge of hot-rodding a '73 Chevy P30 Step Van for their first big build without Aaron.
