I think this has ben discussed but, yes it does make me disgusted when I see this happening to a Benz. I worked at a car wash part time and their was, here and there, a Benz or two that would come with neglected rims and swirled up paint. My neighbour bought a 1984 190E and she neglected it for the 3 years she had it, and then sold it for the new Jeep Grand Cherokee which is on it's way to being neglected also.
It is a sad world sometimes when it comes to cars.
