Mark was on the show for episode 19, which ended up being two parts. Throughout that episode we learned about how Mark got into cars, and how Targa Truck evolved into the beast that it is. In this episode, we get a glimpse into 3 major events that Mark had visited and documented just recently; The Optima Ultimate Street Car Challenge, Pikes Peak, and Sema. To end it off we hear a bit more about that crazy machine of his, Targa Truck.
