Customized weatherproof car covers

Hi guys,

I'm looking to purchase outdoor weatherproof car covers for the Grantourismo and DB9. Any recommendations on good quality customized covers? I'm actually quite anal about car covers, as they tend to leave scratches on the car's surface. However, there's gonna be some construction works in the area. So, I'm left without much choice if I don't want the cars to be covered in layers of dusts. It's the lesser of two evils...

Thanks in advance

Eugene
