It appears the car park of my new flat is a death trap for cars in the autumn. I currently have a hire car which has been dented to hell from all of the falling acorns. I obviously don't want this happening when I get a new car, so what would be the best option to protect my car? I was looking at car covers as a few others in the carpark use them, but I don't know if it would actually stop the dents or just reduce them?
