I bought my C320 wagon last year. It's 2002 model. I didn't have any major problems with the car, but what's worrying me is the oil level warning that seems to pop up from time to time. It might be just burning oil. I was told at the dealer that it burns a liter/2kmiles. Other than that everything is fine except for the passenger head rest that stopped working after a while. The ride is very comfortable, but the aerodynamics are very bad. I can't open the driver's window without my head being blown away.
