well, my experience with autozone is o.k.... I'm actually a store manager with them, my store is in decent shape, but when we have inventories, I have to go to the "other" autozones...the other store managers for the most part are idiots who have no respect for my car, they ask me how fast it is, I tell them it should run 11's, this "store managers's" response was "yeah, I used to have a neon that ran 11's on motor" I was like, "what was you trap?" he said around 100....I walked away.. This other store manager has a bmw five series from the 80's..he swears up and down that since his car was made for the autobahn, he'd beat me from a roll of 60-120...all I can say is I want to slap the guy
