good morning, just a question, I was wondering if all 1992 500sel models were equipped with the rear sunshade? if so was it standard? I am the second owner of my car and I don't have one that I know of. can some one please add a pic of where the button or switch is located? also can I order one somewhere? it gets awfully hot in B-more in the summer. this is a wonderful thread, a wealth of information, thanks.return of the MACK.
