Last weekend, I had to park my 2009 R/T under my office building while away for a business trip and I bought a generic car cover from COSTCO for $33 and it fits like a glove.

The XL size is the only one that fits. It has retaining straps that attach under the car (front and rear) it really is great car cover using quality NOAH-like material.

I would never leave this car cover on the car outside exposed to the elements. But, in a car garage, it's certainly good enough to keep prying eyes off my car and from touching.
