Barry White, a Hot Rod superstar, is struggling to find a wreck to work on for the upcoming Kruse Auto Auction in Las Vegas. He wants to build a'super muscle' car that looks like the 1960s but drives like 2005. After trawling junkyards, Barry has run out of time. He finds an old wreck belonging to his daughter Jen, but she storms off after hearing the news. The Speed Shop emergency turns into a family feud, and Barry's team tries to turn a clapped-out Chevy Chevelle into a show-stopping muscle car in just four weeks. The cost of the car and Barry's money back are uncertain, and their fate lies in the hands of fickle buyers. Barry's money, reputation, and family relations are on the line as they try to pull off the project. The story highlights the challenges faced by a talented team in transforming a seemingly simple car into a stunning masterpiece.

Barry White is attempting to recreate a '71 Plymouth Road Runner for the Silver Auto Auction in Reno, Nevada. After discovering the rusty Road Runner, Barry buys a second Plymouth to create a Super Muscle Car. His designer, Chris Brown, suggests they create a GTX, the top-of-the-line Plymouth muscle car, using a MOPAR Hemi engine. However, the project runs out of time and costs Barry more than he initially wanted. As they get into their Frankenstein creation, they realize it may have been a mistake. MOPAR fans are hard-markers and fiercely protective of their brand. Barry and the team must decide whether to create a GTX to loosen the cash or leave with a monster no one wants.

Barry White buys '69 Camaro shell from a wrecking yard, but it turns out to be cursed. The build is delayed due to hidden rust and dodgy bodywork, causing him to spend more money than planned on new sheet-metal. Strange things happen, such as the super-charger not fitting the engine, wrong parts being delivered, and the engine bay catching fire. The team dubs the Camaro "Christine" after Stephen King's killer car. Barry receives help from the Corona Police Department and muscle car fans, and the well-drilled machine works perfectly. Christine is ready for auction at Jackson Hole, but Camaro owes him $40,000. The auction starts, and a rival fully-restored Camaro goes under the hammer for $25,000. Will Christine's curse mean Barry loses his shirt?

Class is in at Barry White’s Speed Shop. Five students from the local Hot Rod University volunteer to help Barry’s team turn a clapped-out ’70 Pontiac Le Mans into a brand new GTO for the Silver Auto Auction in Portland, Oregon. With just four weeks to complete the transformation, it seems like a good idea — until Barry finds the pitfalls of playing teacher and producing a Super Muscle Car at the same time. There are speed bumps at every turn. Seems no one did the homework on GTO parts — the crucial front-end is missing in action. And the promise of a job to the best student turns the classroom into a Bullpen. The students spilt into A and B teams creating a distraction just when Barry needs results. If that isn’t enough, word is there’s no money at the Portland auction. Barry’s favourite buyers aren’t coming. GTO 101 is shaping up for disaster.

Barry White's speed shop is struggling to turn 10 wrecks into auction showpieces, and morale is low. To revive his team, Barry plans to build a green, super-muscle dragster based on a '60s Chevy Nova,' 'Gangreen'. The team is excited about the car, as it brings back memories and motivates drag fans. However, Barry knows that putting a drag car under the hammer is a big gamble, as there will be limited buyers and it won't be the car to take shopping. He encourages his young paint and body guy, Todd, and challenges another of his charges, Branden, to get an old shop dragster ready for a showdown at the end of the build. The team is about to find out if they can make a race-certified, street-legal, fire-breather monster in four weeks.

Barry White is transforming two Mustang Muscle Cars for two different events: the SEMA awards and a Super Muscle '69 Fastback for auction. The first priority is to transform a new '05 Mustang V8 into a Boss-inspired monster for the 'Best in Show' at SEMA, the auto industry's biggest showcase in Las Vegas. The old '69 resurrection risks taking a back seat, so Barry invites his friends at the Beverly Hills Fire Department to pitch in after hours. To lure these muscle car fans, Barry paints the car fire-engine red. The stage is set for a Mustang duel, and double trouble for Barry White.

Barry White's Speed Shop has been taken over by the Beverly Hills Fire Department, or at least, fire-fighting muscle car enthusiasts who've moved in to help him rebuild his 1969 Mustang Fastback. The Mustang was a classic muscle car of its era, but the wreck he found wouldn't even turn heads in the junkyard. With only a month to turn the dilapidated Mustang into a Pony car for the prestigious Kruse Auto Auction in Las Vegas, Barry has the help of fire fighters providing much-needed labor. The rivalry between A Shift and B Shift is fierce, and Barry is stuck in the middle playing peacemaker. As the firefighters work fast, parts guy Chris Brown can't keep up, and Barry's workshop is filled with agitated fire fighters. The situation is a recipe for disaster, and Barry has never had to handle anything like this before. The question remains: will the firefighters walk out, will Chris find the parts they need, and will the Super Muscle Car version of the Mustang Fastback get finished?

Barry White's reputation as an award winning hot rod builder is on the line. He has a crazy idea to recreate a '60s Stock Car — in race-trim, but street legal. And not just any Stock Car; he's asked legendary race car driver Parnelli Jones for permission to reproduce his 1964 Mercury Marauder and he doesn't want to let him down. Normally Barry needs four weeks to transform old wrecks into auction drawcards, but this time he only has three. He's thinking a rough and ready stock car should be any easy build. Until he finds out nobody makes the parts anymore. Adding to his worries, he doesn't have his normal team of workers and has to call in some family favors. The speed shop is stressed to the max, so it's all hands on deck. But will everyone pull their weight? He has two deadlines, the McCormick auction in Palm Springs, and an assessment of his work from Parnelli Jones himself. Will he make the grade and make some money?

Barry White, a 25-year veteran of the Hot Rod business, is taking a shortcut by finding a '71 Ford Torino in near showroom condition. This is a perfect blank canvas to transform into a hot street machine, with a more expensive upfront cost of $12k compared to his usual 3 to 6. Tony Correia, the body guy, thinks Christmas has come early. For the first time he only has to tweak the panels to exaggerate the factory lines. While designer and parts guy Chris Brown believes he has an easy street with a few parts to find and a reasonable schedule. A team of cyclists also wants to participate in the build, further exacerbating the team's workload.

Barry White and the Speed Shop team are exhausted from transforming a rusted wreck into a powerful, super muscle car. With only one car left to build, Barry aims to recreate the spirit of the '69 Dodge Dart by building his own Hemi Dart. After completing nine previous cars on time, Barry is confident in his ability to build the car. He commits to selling the Dart at the Russo and Steele auction in Scottsdale, Arizona, at any price. Designer Chris Brown plans to inject Rock and Roll into the Dart, contacting 80's band Poison. The "Poison Dart" is a perfect fit, but Barry must convince drummer Ricky Rocket to give the car his blessing. 4 weeks. An implausibly powerful car. A rockstar to wrangle. Selling at any price. Barry must pull off the biggest challenge he's faced in the series, as if the Dart misses the target, it will cost him a fortune.
