I would not hesitate when it comes to comfort or drive-ability. I may hesitate when it comes to putting that kind of miles on it. It seams that once SLK's get over 50K miles they start to take resale value hits. I have 70K on my 2006 and it has crossed that threshold so I just run the wheels off of it now with no problems. I'll probably keep her forever and don't care about resale value, but something to think about.
