Got a cover on carcovers.com. Total BS, doesn't fit snug and let's the water through. No go... Need something well made solid that fits 72 fast back. At least during the summer months.
Thanks in advance.

As plenty others have already forewarned, your desire for a "waterproof" cover for outdoors use during rainy conditions is flat-out suicidal to your car. Any cover that is totally waterproof will not breath. So it becomes a water "trap". Even on concrete, when the rain ends the wet concrete under the car evaporates-up, and becomes trapped/tented under your cover.. Paint blistering, rust, corrosion of all fasteners and un-coated metals, mildew, that's what you're going to get with a waterproof cover.
Most covers designed for outdoor use are breathable "exosmotic" covers that allow moisture to evaporate OUT of the cover, but "restrict" water from coming in. They are described as water "resistant", because that's the best you're going to get. In a light rain, it'll keep your car dry. But in a medium/heavy rain, or extended light rain, eventually the fabric becomes saturated and water begins to leach through. Also, most any fitted-cover is sewn, which means you have stitched seams. The stitched seams are not resistant to water (because a sewing machine needle has punched holes down the whole seam), and water gets in on the seams. It is what it is.
My advice?? Don't sweat the water getting through and your car getting wet. Your Mustang isn't a witch LOL... The good thing is, that cover will dry-out properly in the wind/sun, and the car will also dry-out with it. Moisture will not be trapped. And don't leave the cover on for extended periods. Every several days when it's sunny out, let the car sit in the sun with the windows cracked with no cover for an afternoon or full day, then put the cover back on.
A dry car is a happy car. But putting a truly waterproof cover on a car does not keep a car dry. Quite the opposite. It creates a hot-house, like a green house... You could grow plants under there. Don't do it.
