John Tavarez, extraordinary sales associate, exceeded my expectations this morning. I heard a strange clicking/ringing noise underneath my hood, and thought I should go to AutoZone to check it out. John examined hoses, belts, and other stuff. Everything looked pretty good; however, he suggested that I keep a printout of his report for my mechanic, just in case. I have been going to this AutoZone for more than ten years, and they always go above and beyond.
