I have been using Rock Auto for a few years now and so far no one has comes close to matching price, availability of parts and service. Rock ships from various locations around the country. When there has been a problem it was dealt with quickly in a no non-sense manner. The only thing that concerns me was recent shipment of spark plugs I received from 5412 South 24th Street, Fort Smith, AR. The sparks plugs where just put in a box with no packing material at all. All other shipments from other locations where packed properly for protection. Maybe it was just that one person who did not care. Still Rock is the way to go I just hope don't received anything else from Fort Smith.
