The season begins with Aaron restoring a vintage Harley Davidson in celebration of Discovery's Harley and the Davidsons. The rest of the season is jam-packed with adrenaline-fueled fun. Between a visit from iconic car builder Chip Foose, a trip to Nascar with the Miller Lite team, a Porsche vs. Porsche race and a venture into the business of Monster Trucks - the Gas Monkey Garage has its work cut out for it. The season also includes some of the best builds the crew has ever done, including a'72 Pantera, a '00 Porsche hot-rodded with a Chevy engine, and a classic '49 pickup, which turns out to be the ultimate curse for the team, as they attempt to restore it to show truck perfection.
