I was wondering the same thing. So I went to the websites of a few local ones and checked. Pep Boys and Autozone both have "enter your car and see our stock" features. I don't think I'll be able to get oil filters at the Walmart anymore.I Would think you can get the most frequently changed parts on a volvo like brakes, shocks, plugs, electric window switches, oil air filters at auto parts warehouse. What kind of parts do u think cant be found on amazon or at auto parts warehouse?
