When I used to own a Boxster I got all my parts from Pelican parts. Their return policy was excellent. For instance I ordered a new water pump for my 2001 Boxster and took delivery of it and was planning on replacing it coz the one in the car was old but had not failed. Shortly after I got engine problems and did not want to keep the car. Pelican took the new water pump back after I explained I was not keeping the car.
So Pelican prices may not be the lowest but because of their good service and great forum I never went anywhere else. Lowest prices are not everything.
