I have a Covercraft Weathershield HP. It was very expensive but worth the extra. Very lightweight, waterproof, and easy to secure tight with the right fastenings: mine doesn't move even in very high winds.Fully tailored, mine is a convertible, and the cover is tailored so well that it wouldn't fit a coupe. I've used many different covers on various cars over the years and have found that you get what you pay for.
