Horrible experiences with the staff keeps me from rating this store any better. They carry what you would expect any auto store to have. The staff, however, needs a reality check. Anyone with basic vehicle knowledge can be hired at Auto Zone. Two of their employees, a clerk and a manager, seems to think that they know better than an actual trained mechanic who owns his own shop with an awesome reputation. My mechanic even called to explain to the manager that they sold a faulty merchandise but the manager blatantly refused to speak with him. She went on to explain to my boyfriend and I how their $100 dollar system is very accurate and that our mechanic is wrong. She even tried to have us seek a second opinion. In the end, she ended up honoring their warranty with an extremely arrogant attitude. As anyone can guess, our mechanic was correct and the problem was fixed. The staff here seems to have forgotten how to be courteous to customers.
