O'Reilly Auto Parts is a favorite parts store where customers are treated great. The staff is very helpful, knowledgeable, and super friendly, often taking time to explain what to look for and provide outstanding info. They offer helpful service like changing wiper blades for customers. However, they generally do not install car batteries anymore due to not having time for the service, which is a disappointment for some. Customers are advised to ask for advice on vehicle issues before starting a project.
