I have a 2001 C320 bought it used with 20,000 miles on it and thanks for the warranty. It was at dealer after 6 months for A/C unit not working properly and it made a clicking noise. The dealer was nice enough and found more problems and replaced the gauge cluster because the display lights were not bright enough.
Then after another year or so about 35,000 miles the rear windows did not roll up. Warranty was over so I pulled it apart and fixed it myself. Otherwise dealer would cost me $800 plus.
I did all the schedule maintenance at my regular auto shop. At about 55,000 miles I had the same clicking problem and I told my mechanic that it had happened and when they checked it out it was the motor so I had it disabled. Just to open the dash, it cost me about $300. I also had to replace mass air flow sensor, ESP sensor, and found my motor was leaking oil from the rear main seal.
This Mercedes is junk and will never buy or let any of my family or friends buy one! Any car at 60,000 miles that leak oil from rear main, window malfunction, mass air flow sensor malfunction, ESP sensor, A/C unit problem (twice) and other electrical problems, should be off the road. Compare this to other brands, I am sorry to say Mercedes, I will never buy again.
