I bought the CoverKing storm proof in blue for about $240 incl. shipping. I use it every day as I do not have a garage. I think this is a great cover for the Spider. I previously have owned a couple of Covercraft Custom Weathershield HP covers. They are softer and lighter and, I think, very high quality covers. But the CK is actually waterproof, which is nice, whereas the CC loses its water resistance after a short time. Actually, I don't think that matters much because the water that gets through the CC does not leave spots on the car and the car and cover dry quickly after the rain stops. The wax job is left just fine. But the CK is a little heavier fabric and, I think, will stand up to the Florida sun longer than the CC. Also, on the Spider, the cover fits down low on the tires and so gives good coverage and has stronger elastic than the CC. I think it will stay on in a pretty good breeze better than the CC, for which I sewed on clamps for nylon straps on the front and back. The CK has a nice pocket for the antenna and, unavoidably, one for the shark fins for those of you unfortunates who have them.
