yes i am talking about the roof. I know there are aftermarket systems that are essentially plug-n-play for the newer chassis 171 as well as SL and CLK. They allow opperation of the roof from the key or one touch from the interior roof switch so you don't have to hold it. and they allow the roof to opperate below 30 mph. I don't want to operate the roof at high speeds just when i am in a parking lot and parking. My Porsche allows me to operate the roof up to 35 mph and that is factory. So the questions is has anyone seen these for the 170 chassis? i read somewhere that mercedes acctually had a dealer installed option that at least allows for remote open of top
