Personally, I think indoor car covers can cause more micro-marring than they are worth unless the car is always clean and dust free when the cover is placed (the latter issue can be reduced by a good sealant of course). That said, if I was going to buy a car cover, I'd buy it from California Car Covers. They are not particularly inexpensive but I've heard they make very high quality covers and have indoor and outdoor applications.
