Ok, so I was at the dealer the other day and spotted a beautful 1998 c280 sport in immactulate condition. I fell in love with the car immediately. The car runs great and pulls strong, but I have just one question.

When I first test drove the car, the car would vibrate pretty harsly at idle in Drive. Now I was able to keep the car on an overnight test drive, and noticed that after the car thoroughly warmed up, the vibrations dissapeared. At first I thought i was motor mounts, but if the car had bad motor mounts, would the harsh vibrations dissapear after the car was warm?

Just wondering as I am in love with this car but am hesitant to put a deposit down on it due to the rough idle.

Anything helps.

Thanks in advance.
