Ive seen two episodes, I admit it was funnier than I thought it would be. It has the potential to get old fast though, as the whole show takes place in the shop or the office.
Its all actors though because I know the guys personally who own that shop and almost all the people on their are actors. Kinda lame when my friend told me about it thought it was gonna be along the line of american chopper kind of show. They do some awesome work their and its not really reflected in the show.
