A hard Standing car area is ok for a short while, then the old lady. mother nature decides your car needs to rust and blend in with her autumn leave trees. And then your car is destined to the car repair Shop, garage, or chop shop, depending on how bad the damage it.
My advice would always be to park your car under a car port, in a garage , (The Best) or buy a bike!
