If it's a cover for inside use, here's what I did, and saved a bunch of money. I got 3 of the large cheap microfiber blankets at a store (Walmart or just about any similar store, they're pretty much all the same), then had the wife sew them together. I trimmed the excess off and the wife added them as 'extensions' on the sides (the widest part of the car). They cover the entire car, are EXTREMELY soft, do absolutely no damage to the paint, are very light, so easy to throw on and take off and only cost me about $90 total.
Here's a shot of what it looks like.
It may not look the best, but it has worked far better than any other cover I've used, and I've used some really expensive ones, including the California Cover. I do
not like the kind that uses spandex to keep the covers tight around the car; they are difficult to put on and remove, require that you stretch and drag the cover across the paint to get it around the corners (which creates a high wear area on the paint), and are typically heavy and expensive, and they're difficult to wrap up properly (like fitted bed sheets). I can easily roll mine back across the car, flip up the sides, and it's done. Putting it on, I just sit it on the deck lid, flip the sides down and unroll it across the car. Done. I get zero dust through it, and it still allows the car to breathe, so it does not trap moisture.
