Now that the doors of their new shop have opened, the Gotham team embarks on a project: a restoration of a 1953 Buick Special, followed by an unprecedented endeavor – the conversion of its gasoline engine to an electric powertrain.

Following a significant misfortune, the crew now concentrates on selling a heavily modified motorcycle for quick money, with the aim of securing their next worthwhile vehicle.

Seeking to salvage a failing agreement, Shawn encourages Mark to undertake a project steeped in sentimentality. This presents an opportunity for the garage to make a favorable impression on a prominent, newly acquired client.

Mark continues to stretch the limits of possibility with his latest projects: he's completely transforming a minivan into a vehicle worthy of a rock band, and he's applying the Corvette aesthetic to a boat.

Shawn was on the hunt for components to facilitate a significant exchange, while Mark meticulously finalized a kit car project. A visitor, unexpected and somewhat startling, appeared in the garage: Caveman’s mother.

A significant breakthrough arrived for Mark and Shawn. The team began by restoring an old car for a local competition, and then shifted their focus to a genuine vintage racer, undertaking a comprehensive series of improvements.

While Mark meticulously restores a 1947 Dodge Power Wagon of military design, Shawn settles into the driver's seat, assessing potential purchasers for a 1960 Plymouth XNR.

The crew considered the opportunity before them – a chance of a lifetime, undeniably, yet burdened with significant consequence.
