With the new shop open for business, the Gotham crew upgrades a 1953 Buick Special and then attempts a first: converting a gas engine to electric.

After suffering a massive setback, the crew focuses on flipping a souped-up motorcycle for some cash and finding their next great trade-up car.

As Shawn tries to rectify a deal gone bad, he pushes Mark to take on a sentimental project. The garage gets a chance to impress a splashy new client.

Mark pushes more boundaries with his next two upgrades: overhauling a minivan so it’s fit for rock stars and giving the Corvette treatment to a boat.

Shawn pursues the pieces he needs for a big trade while Mark puts his stamp on a kit car. The garage is treated to a surprise visitor: Caveman’s mom.

Mark and Shawn finally make progress on a big deal. The crew fixes up a jalopy for a local race, then dives in to upgrade a legit vintage race car.

As Mark overhauls a 1947 military-style Dodge Power Wagon, Shawn finds himself in the driver’s seat when he surveys buyers for a 1960 Plymouth XNR.

The crew collectively weighs the opportunity of a lifetime — one that entails a great deal of prestige, but comes at a hefty cost.
