I purchased a 2001 E320 4matic with 12,619 miles on it in March and have been very happy with the purchase. Apparently, with all the things to absorb in a test drive I did not hear a slight clunking noise from the back. What is happening is if I am in traffic and I take my foot off the accelerator and then a few seconds later apply some gas I hear a slight clunk coming from the rear - sounds like a universal joint (I think the Merceds equivelant is a slip disk). I bought the car from a dealer (paid $32,200), I have the Starmark program (and I bought a 4 year 100,000 mile warranty from AAA) so getting it fixed won't be an issue just wanted to get some feed back on what it might be and if this is common with E320's of this year. BTW I did check CarFax and the Mercedes repair history and the car wasn't touched except for normal maintainence (oil changes etc). The car was exceptionally clean - not a nick, scratch, dent on the paint, the leather was clean etc..., cd changer, Bose system. I had a Volvo S80 Turbo that was transportation. Driving this car is, well, like a mini vacation.
Thanks,
Jeff
