I've been going to Superior Auto Care for a number of years for the tougher to diagnose and fix issues as well as to get professional opinion on whether a repair is worth the coat. They always resolve problems other mechanics can't figure out and have always steered me right toward the right repair or advised against work when it didn't make sense (like repairing an A/C when the car should really be replaced. I've used Superior exclusively the last year and very happy I did. I recommend them without reservation.
