Robert pursues an ambitious electric conversion on his BEAST of a K10 truck. Along the way, he test-drives two fully-electric cars: the Army's latest tactical vehicle and the world's fastest-accelerating production car.

As a child, Robert's true love of driving came from his mom, a real daredevil on the road. She left him her old Benz, and he treasures it to this day. Now he's restoring it with the help of his son, Exton, and a crack crew of diesel experts.

Robert LOVES the design of his '66 Buick Riviera -- but it's one of the most fuel-inefficient cars ever made. In the 1960s, it was sold as "the car of the future." Robert plans to perfect the Riv by updating it with a stunning, one-of-a-kind rebuild.

Robert has an all-original, low-mile '85 El Camino. But as he often says, "She's perfect, so I have to start over." He's out to turn it into a meaner and greener off-roading champ. When it's done, he takes his wife Susan on a hair-raising maiden voyage.

Robert flexes his negotiating skills to buy a used car he's always wanted. Of course, the first thing he does is tear it apart and rebuilt it. It's a journey from the past into the future — a fitting end to his long strange trip into car restoration.
