I really enjoy reading all the Q & A in this forum. They are all very informative. Anyway I just joined in. I just acquired a 2000 E320 with 76000 miles on it. It drives great. The only concern I have is when the road is a rough, with small potholes, I can hear rattles coming from the headliner, like something is loose, the headliner is hitting the top. Any info/solution will be greatly appreciated. Thanks.
