The rear bumper guard just sticks to the top of the rear bumper to prevent scratches when loading and unloading from the trunk. I've attached a link with picture.Can I ask what the bumper guard looks like? I've been thinking of it, but the dealer has no pictures and couldn't find any online either. Is it body color, chrome, black? I have two kids and am thinking that I'm bound to get scratch sooner or later.
