I did it, bought another W210. Garage kept in as good condition as you could find. Now comes the issues. I know almost nothing about SLS. The suspension is extra bouncy the rear struts have been replaced with used OE struts by the previous owner, no change. My guess from all my research is the nitrogen balls need to be replaced. But that is not my question. I am looking at the car and the rear seems to sit lower than the front and I can't tell if that is how it is supposed to sit or not. Looks to me like the front is almost overextended. Wondering if anyone has any advice as what to check.
