I just recently purchased a really nice condition 2002 E55. It has 210k miles and is still a beast. One thing I notice though is that the ride quality is terrible. It has newer bilstein shocks all around and brand new Cooper tires on the monoblocks and you can feel every little crack in the road. Its bone jarring how hard it rides. Is this normal? I had a 1996 and a 1999 e300 diesel before and they rode very nice. Im wondering if I swap out the shocks to basic w210 shocks if this would help?
