When Richard buys a VW Microbus no one really knows the mechanics of this German car. Later, Richard and Aaron discover that the Fired Up garage is attending a demolition derby and Richard has a trick up his sleeve to send his former employees reeling.
Aaron and his team attempt to get the ’71 Challenger build to accept the 2015 Challenger technology. In the process, they create a one of a kind resto/mod. Richard buys a busted up ’34 Plymouth and the crew takes the ’57 Shorty bus for a test drive.
Richard buys a ’69 Malibu only to realize there are massive issues. Aaron crashes into a ’68 Coronet on the GMG lot. Richard travels to St. Louis to buy a tricked out ’79 Camaro. Motley Crue performs at Gas Monkey Live grand opening.
Richard sells the ’79 Camaro to prepare for Barrett Jackson, the biggest auction of the year. Aaron’s team builds a ’68 Impala while Richard and Dennis buy a ’64 Corvette Stingray. Richard pulls the ’66 VW bus, ’69 F100 truck and ’76 C10 to auction.
It’s showtime at Barrett Jackson with wheeling-and-dealing throughout the week showcasing the excitement. Richard’s Stingray arrives just in time for the start of the auction. Meanwhile, Aaron attends NHRA in Vegas to see how team Gas Monkey performs.
While Richard takes his ’29 Packard to compete at the elite Concours d’Elegance at Pebble Beach, the Monkeys race to complete their motorcycles in their big build-off.
When an old friend of Richard’s offers him $200,000 for a Knight Rider KITT car and for David Hasselhoff to appear at his 40th birthday party, Richard can’t pass up this offer. He sets out to not only find an 80’s Trans Am, but the Hoff.
It’s a race against time as the Monkeys rush to finish the KITT car. Richard’s on edge because he’s worried that him and Aaron might not make it to the Las Vegas birthday party with the car by the deadline. They also don’t know if the Hoff will show up.
Aaron's plan to build a “junkyard Porsche” capable of going head-to-head against Richard’s 2015 Porsche 911 Turbo S goes awry when the expensive conversion kits he’s bought don’t fit as planned.
