Shipping was quick and the prices were great. - Hillenbrand

Verified Customer

Parts variety and selection is excellent, pricing is very competitive and the free shipping was just the bonus I was looking for. The parts arrived in days and the eMail with tracking link provided vendor confidence. All parts from the Bilstein Struts to the APA Heavy Duty Urethane Mounting Bushings were delivered as promised. I am confident that I can count on PartsGeek.com for all my parts needs for my two Volvo S80s. An eMail Invoice would be nice, so print Order prior to final submission. - falcon123456
