I've never used these guys, but I have been to their store and observed their operations. Everything I have ever heard about their car service has been negative. They charge way too much and their mechanics don't know what they are doing seems to be the common experince. I've found for my business vehicles, when I have to use a national chain, Firestone has consistently given me excellant mechanical service. Their prices aren't too bad and they have the service level ratings of their mechanics posted on the premises, and in general do excellent work. I have never had an experience like some of the things I hear about from these Pep Boy guys, like oil pan drain plugs popping out after an oil change, etc. I can't help but feel it is because Pep Boys uses a lot of lower paid guys who claim to be mechanics - I like the fact that at Firestone I can usually look out in the bay and see a few grey haired guys who look to be on top of things.
