Agree on the body roll. When I picked my first E53 from dealer I went back after 2 days to complain about the doors as they will only shut completely if banged hard. They told me that's the design. In E70 one light hit and it closes the door.
Once thing I do not understand is why they cannot squeeze a in-dash 6-disc changer as std. equipment when every other manufacturer has done it. Maybe they want to make more money by selling a 6-disc changer.
