I've been watching Fastest Car and Rust to Riches. Both fun shows for car lovers. The Fastest Car show is 3 backyard mechanics racing their "sleepers" against a supercar, but they do a pretty good backstory on the four racers in each episode and then race em at the end. All the winners compete in the finale. They do a great job of establishing a heel in every episode, and I always have a hard time picking the winner. One gripe is that they rarely focus on the motor/trans in each car. They gloss over it usually with comments like "just a little turbo and a bottle in the back" but they'll never tell you what the motor is or how much boost they're running. Rarely will they come out and say "it's a sbc 350 with 12 pounds of boost at a manual valve body powerglide."
Rust to Riches is just another random chop shop that likely has five times the employees they show on screen, and 100x the cash flow they claim to have. "Damn we can't afford to buy this floor pan from the scrap yard for 50 bucks, can we trade you a set of used tires for it?" But, the projects and trades they come across for most cars are pretty slick. Like the Fastest Car program, I wish they focused a little more on the details of the build and not just the before and after. It seems like on some episodes they show the car being cut up and then in the next frame it's painted and the interior is totally finished.
