I have a 2004 SL 350. I noticed the aluminium roof at the rear corner (where the roof hinges when opening) corroding in 2006. I was shocked that this should happen on a new car with an aluminium roof. Mercedes fixed it and assured me it was not a normal problem, and that it was permanently fixed. In 2009, the roof corroded in the same place, and this time on both sides of the roof. Mercedes fixed it again and assured me there was not a fundamental problem.
Quess what - its 2012 and the corrosion has come back in the same place. Mercedes are looking at this as I type, but I was wondering if anybody else has had this problem?
