Their knowledge is only as good as the products they produce with it. yes, they dan do a lot, but they are producing tacky, ugly and horrific cars. They may be knowledgable, but I would never take my car there.it may be tacky as hell that they're on tv, and they act like it's a suprise and everything, but those guys know more than any shop around here, that's for **** sure, they usually use pretty decent equipment...
