Hi all ! I'm new to not only this forum but forums in general ! I have a couple of mercedes at the moment but my question relates to a car I have just been offered yet have never come across before ? I'm told it is a 1990 series 400 but this one is a cabriolet ! I've never seen one before and just wondered if anyone could shed some light as to wether or not this is genuine or an aftermarket conversion ? Any help would be greatly appreciated ! Many thanks folks .
