When Aaron presents the idea of upgrading Richard’s new ’71 Dodge Scat Pack Challenger R/T that he bought at auction by transplanting the drivetrain from a brand new 2015 Dodge Challenger Scat Pack, Richard agrees to let Aaron tear apart two nearly perfect cars to make it happen, only to realize that this may be the most difficult build the garage has ever faced.

Les and Seth visit a customer with a garage full of amazing vintage cars. Against his kids' wishes, Les offers big money for one of the guy's golden oldies...but can he close the deal? While a male stripper gives Byron the slip, Karen stumbles making a big deal and Ashley forces a customer to kiss a Gremlin for cash.

With Les and Seth away at the Autorama car show, and Ashley in charge of the store, the employees go a little crazy. Karen gets caught putting on a fashion show during store hours, and Bobby J gets called out for being rude to a customer. Seth accuses his sister of being a bad manager, but Ashley gets the last laugh.

When an argument with Seth leaves Ashley in tears, Karen attempts to broker a peace deal. Seth refuses, but Karen's gesture brings her and Ashley closer together. Plus, Bobby J takes a joyride on two-story tractor, and a watch snob finds himself on Seth's bad side.

A ventriloquist leaves Karen and Bobby J speechless, and an angry MMA fighter takes a swing at Byron. Plus, an odd couple delivers one of the biggest surprises in store history when they try to sell the Golds art they claim is worth over a million dollars. The paperwork is fishy, but the Golds bring in an art expert who believes the paintings are genuine masterpieces by grandmasters.
