Locally I have many options as far as parts stores go. I've got Autozone, O'Reilly's, Advance Auto Parts, Carquest, and NAPA. Typically, I shop at Advance Auto Parts simply because if they don't have a part in stock, they can drive to the end of town and pick it up at the distribution center that has everything. In other words, my wait time has never been longer than two hours for any part... With that said, I am just curious how these businesses compare as far as parts quality goes. Is there a clear winner, or should I simply stick with what has been working for me?
