I have a genuine Porsche Boxster cover that I used indoors only. No rips or tears. The car side of the cover is ultra soft like fleece. The outside of the cover is very nice silver color with Porsche logo on the front and Boxster logo on the back with a window for the rear plate.
I sold my 986 Boxster a couple of years ago and accidentally kept the cover.
I now have a 996 911. If you have a 911 cover and want to trade for a Boxster cover, let me know! I think this cover might also fit a Cayman. I almost had it on my 996, but the car was just a little too long. The roofline didn’t seem to interfere with the cover fitting.
