Barry's looking for a new challenge and as far as he's concerned, there's only one choice - an El Camino. His newest fabricator, Bobby, has an emotional attachment to the El Camino; his dad gave him a '69 when he was a teenager. Although not Bobby's car, Barry's '70 El Camino wreck tugs at Bobby's heart. He's helping rebuild this one for his dad, who'll be 'looking over his shoulder' as fiercely as his boss. Barry's money and Bobby's family ties are at stake - and they only have four weeks to get the car ready for auction.

Barry, Chris, and Tony are searching for two racing legends, Dan Gurney and '68 Mercury Cougar, to transform it into a Super Muscle Car classic racer, the XR-7G. Dan is an old-school racer who flew the U.S. flag in Formula One, Indy, and Le Mans. To get Dan's blessing and endorsement, Barry must complete a lot of work and perfect everything to entice the legend to join the project. Barry's daughter Jen, who loves old-school monsters and the raw engineering of early classics, is also interested in the project. Jen is moving away from home and living in her own apartment, marking a turning point in their lives. Barry's mother, Becky, has to say goodbye to her only child, while Barry gets her bedroom back for car stuff. Despite this, they still see each other every day at the shop.

Barry, a car enthusiast, is planning a street-legal Thunderbolt with a 427 V-8 engine, fibreglass hood, oversized rears, and racing seats. He plans to start his own DIY auction at the Speed Shop instead of risking an open auction. Barry, Becky, and Chris hope to attract high-rollers to participate in the bidding. The DIY auction is a first for Barry, but if he can convert his building skills into entrepreneurship, he has a chance. Becky and Jen become event managers, a first for both. Will they have to block off the street? Who's doing the catering? What about parking? Permits? Auctioneer? The event snowballs into an logistics nightmare. Tony, a paint and body guy, may even bid for the Thunderbolt himself. This could be their most eventful auction yet.

Barry and his team are transforming a no-frills speedster into a swaggering swan with the help of O'Reilly and MOPAR guru Ronnie Jenkins. They are also launching a DIY auction to sell the RoadRunner SMC version online, hoping to attract buyers from all over the world. Bidders can watch the build progress on Barry's website and bid on the final two days of the auction at SEMA. The SEMA showstopper will be a big screen projector and loud auctioneer, while the team will smoke up the Road Runner before adoring fans. The team's entrepreneurial spirit is ignited by their DIY auction and the opportunity to sell their creation online.

The Muscle Car Era has made Barry White a happy man, along with his high-dollar customers who buy his creations at auction. But this hot rodder and drag racer is always looking for a challenge and Barry finds it one morning during his pre-breakfast stroll. Outside his neighbor's house sits an American classic; a '57 Chevy, with a 4-sale sign that Barry can't walk past. The only question in Barry's mind is whether to turn it into restoration project or a quarter-mile burning dragster? The answer comes only too quickly, as the body turns out to be junk… too much time, too much money for restoration. Barry decides to head for the track and give it the Mother Of All nose jobs and a monster motor to try to hook a drag-racing fan. He decides to hold the auction at the Wally Parks National Hot Rod Association Museum. And if that's not risky enough, Barry wants to try a new way of selling; a silent auction, with sealed bids. It works for Real Estate auctions, but can it work for Barry?

Barry White and his team have always been into recycling big time. They rebuild left-for-dead junkers into stunning showroom Super Muscle. But this time they're going for broke; full-on, tree-hugging torque with an enviro-friendly '71 Chevrolet Chevelle. Just how do you build a 'green' hot rod? You need more than a change of color. The plan for this eco-overhaul calls for improved mileage, reduced emissions and non-toxic paint, just for starters. And to help Barry 'correct' this former gas-guzzling Chevelle, he gets extra muscle from a possie of Prison Guards who know all about Correctional Facilities. In four weeks they'll need to bring the last of the original oil-thirsty Muscle Cars into the climate-aware 21st Century, in time for Barry's second 'home' auction. But who wants to buy a 'Hippy Hot Rod'? Paint and Body guy Tony can't think of anyone. But Barry, Jen and Chris think it's the way of the future. Can Barry's Speed Shop turn into a Green House?
