in my personal experience any out door car cover can turn into a nightmare. so easy for them to scratch the paint when the wind gets under them.

is it for long term storage? have you thought about one of these portable garages? http://cgi.ebay.co.uk/Large-Folding-...item5ad9f8dfe7

bloke at work has recently had one for his stag and can't fault it, keeps the weather off the car and is fairly easy to get the car out of as it just folds back. will probably be getting one myself soon to store my kit car over winter as my dad is being selfish and knocking his garage down as he can't fit his car in it
