I have an SRT Coupe that rarely gets driven. It sits in my back driveway which is partially shaded, I have a fitted cover on it and a Seal Skin cover over that that goes all the way to the ground all around. It has been parked like that since 2015 and still looks like new. I will add that it is very dry here, seldom does it rain and the humidity stays quite low. I have replaced the Seal Skin cover a couple times.
