Because your 2011 Cadillac DTS will be parked outside for a while, you’ll want to ensure the car cover you purchase is specifically designed for outdoor use. This will ensure it adequately shields your vehicle from harmful UV rays, pollen, rainwater, and anything else Mother Nature throws your way.
Most car cover manufacturers—such as Seal Skin Covers and CarAutoCovers.com—sell their outdoor 2011 Cadillac DTS car covers for approximately $120, but cheaper options are usually available. WELLvisors, for example, sells a decent outdoor car cover for only $100, and you may be able to find secondhand covers for sale on Ebay.
