C Pillar which models did it affect?

Yeah I dont think it is specific to any model, but I haven't even heard of many people having this problem...although it is "well known." Maybe it could happen as the roof slowly settles/drops slightly over time because of use? Either way, lots of possible fix ideas at slk32.com.

It's the pillar directly behind you and to the left. It slants forward and is part of the roof...The SLK only really has 2 pillars.

cmorosco's thread about his C pillar problem. It is the fat support on the back of the roof. When the roof folds, it sits in the bottom of the trunk. http://www.benzworld.org/forums/forums/thread-view.asp?tid=1198048&posts=12&fid=26
