Derek and Sean Bieri head back to Zweifel Motors to revive an Oldsmobile station wagon Derek has been eyeing for 16 years. But the two get off to a bad start when the engine starts knocking on heaven's door. They'll have to swap the drivetrain and revive the sagging suspension if they hope to hit the road in the Black Hills of South Dakota.

Derek goes off the deep end with an '80s icon, the DeLorean. It's been wrecked, painted, and doesn't run, but Derek and his team of friends plan to change all that with a good old junkyard LS V-8. See if they can power this time machine with carburetors and make it to LS Fest in Bowling Green, Kentucky.
