I notice a periodic vibration when my car is idling or after a cold start. Seems to run fine except for the vibration. Car has 176,000 miles mostly freeway. Rebuilt trans @140,000 mi, new plugs and wires @160,000 mi

I'd say you have long been due for new motor mounts.

In a strange way I suppose this IS car audio!

Motor mounts . . . yeah. That should improve the ride AND the audio!

I don't now if this will help but the 2000 ml430 has a recall on the vibration damper. This is a quick repair and it's a free repair. This is NOT "Good, Good, Good, Good Vibrations" like the song says.
