O Reilly Automotive Inc
One of North America's largest auto parts retailers, O'Reilly Auto Parts runs thousands of stores serving both do-it-yourself car owners and professional mechanics, offering everything from batteries and brakes to engine parts. It was founded in 1957 in Springfield, Missouri, when Charles F. O'Reilly and his son "Chub" resigned from their employer rather than accept a forced retirement and a move to Kansas City, betting on themselves instead. Today its "Professional Parts People" staff even read check-engine light codes and test batteries for free right in the store.
