I've had a 2005 E320CDI for a year now with no real problems. Car had 108K when I bought it from a dealer; has 119K now. The quality of the interior materials and paint and appearance items is impressive, although I believe my car was mostly garaged, which helps. I really like the ride, drive, quiet, and economy.
I have heard the occasional pop-creak from the right front suspension, nothing alarming. I read that this is often reported on this series car. My car was completely dealer serviced and I am glad I bought it. I am also glad I did not give $54000 for it.
