Used the VRN part finder on the GSF website to order a wiper arm for a 939 series Alfa Romeo Spider. 1. DPD delivered an open box from GSF to the wrong address (DPD 'kindly' provide photographic proof!), later the driver realised his mistake then delivered the box to me. 2 out of ten for effort, zero for competence. 2. Immediately recognised GSF sent the wrong part (I think it's for a 916 Spider?!) and surprise NOT the GSF website now says no wiper arm available for my car. Zero out of ten for competence. I will be demanding a return authorisation number and refund in store (which GSF don't usually permit for online orders) I see multiple adverse reviews from many customers who GSF have provided incorrect parts to. I had forgotten how bad GSF is and will not use them ever again.
