The original show was going to be "Gas Monkey Garage". That's been their shop for a while now and something they ran under during the Gumball and Cannonball. (Richard has run a few along with Aaron before the Beard) According to Aaron, it's been a 4-5 year work in progress to get the show. The original premise was going to be them building cars, fabricating, etc... Then Discovery had the idea of buying projects and flipping them for cash. It's different to say the least, I'm just glad he got his big break. He's pretty talented (and hilarious in person). You'd love his F100 too Scott, I've got some pics on my phone.
I think the drama has to be added for entertainment effect.
