So I just got my car back from the shop. Ended up having to get my air intake hose boot replaced. Anyway, before starting work on my car, they pulled up the part in their system and showed it to me on their computer. It was $381. I was able to talk $150 off. So they do the work, I go home and look up how much a boot costs. $62.... WTF! I knew it was cheaper to repair yourself, but 85% cheaper! Is it like that for most car parts in shops?
