Perfect for what we need
This car cover replaces a StormProof that had been in constant use for ten years, so the immediate choice was to get the same cover. The StormProof fits better than any of the other covers we tried since 1994, and when we're too lazy to use the center anchoring cord, clips on the back of the front and rear bumper--and the mirror pockets--keep the cover in place during most wind events. One detail is different: The pocket for the Mercedes star isn't as deep and puts a minor strain on the star.
Porsche 993 C4S black car cover
The fit is decent, but not perfect. The quality is good and the material is excellent. If the fit followed the lines of the car, I would rate it near perfect. The seams do not line up with the roof lines nor does it fit the rear spoiler very well. I like the black color and material, but, for not much more money, I would probably buy the Porsche brand cover instead of the Covercraft brand.
