Thomas and Tom acquire a rare first-generation 1959 Chevy El Camino, but excitement turns to despair when the car's condition gives John Klump second thoughts.
Thomas surprises Klump with an offer, and goes on a spending spree, buying two new cars. Meanwhile, problems arise on the El Camino build.
The guys buy back a 1952 Willys Jeep to build an off-road machine! With no buyer, they showcase it at off-road event Rednecks With Paychecks.
Klump returns with the Willys Jeep, but it has been painted the wrong colour. Meanwhile, Thomas and Tom make a deal on a vintage 1964 GTI.
