My 560SEL had a very slight rumble at idle. Not so severe that you thought it would die, just enough to make you think that it was wrong to happen in a fine car such as this.

I replaced both motor mounts and the transmission mount, and the problem disappeared. Idle is now smoother, you can bearly tell the engine is running.
