I bought a 4 layer cover on eBay from usautogears for $30. My car is kept in my garage and I use it just to keep the dust off it and keep the dirt from falling off the garage door as it moves up and down. It's actually overkill as it is supposed to be good for rain and snow, but for the price, it works just great. It has a soft lining so it won't scratch the car's finish.
