funny, the place i usually take my cars to is a firestone, or used to be.
Never had problems with them. I had the same guy work on my car most of the time, now since they moved, and pretty much overhauled everything (except for my service manager, he's cool, and always hooks me up with free stuff here and there, like wipers, and 10% discounts). Whenever i get my oil done there, i watch the new guys do the job...pretending i want to learn how to do stuff...they are cool with it, and they tell me lil things here and there.....
Suffice to say, i trust them more than my dealer, but then again, i've known the service manager since 98, and he's taken good care of my previous car...
my uncle and a few close friends of mine takes their vehicles there too, and no compliants
