Got this for my 2015 Mustang Ecoboost Premium (S550 body). t fits better. It covers the whole car but needs some stretching and is not a very stretchy material at all. You have to do it very scholarly. I expected it to fit better but if you try it will cover the whole car. It's so thin that I think it's definitely not weatherproof, I think when it rained my car got kind of dirty. For the price it is what it is, I don't really regret it. I really only needed one more dust cover than anything else and it works well for that.
