Hello, we have at our SLK left and right at the inner side claddings of the trunk water running tracks. And today my friend said, that probably a small puddle has formed. One does not really see the cause, but I wanted to ask if other 170 he drivers also have that. Can not imagine that it comes by opening the tailgate. Thank you already in advance.
