To stay out of the no-driving zone, DIY car repairers with auto problems often enter the AutoZone. With more than 5,190 stores in the US and Puerto Rico, AutoZone is the nation's #1 auto parts chain. It also has more than 450 stores in Mexico and eight stores in Brazil. The company also operates 24 Interamerican Motor Corporation (parts distribution) branches in the US. AutoZone stores sell hard parts (alternators, engines, batteries), maintenance items (oil, antifreeze), accessories (car stereos, floor mats), and non-automotive merchandise under brand names, as well as under private labels. AutoZone's commercial sales program distributes parts and other products to garages, dealerships, and other businesses.
