I like going to AutoZone because the staff are very helpful and knowledgeable. I have gone to numerous ones and it seems they all know what they are talking about and never seem mystified by my problems. Also if the check engine light is on, on your car they will scan it and tell you the code for free. I know just having them do those can save you a lot of money. Some repair shops charge almost 100 dollars to pull just that code.
