Engine Mount Replacement
About 50,000 Km ago - a MB Shop recommended I replace the engine mounts on my 1999 SL500 which had 200,000 Km on it at the time.
An independent mechs is said - not needed. So I did nothing.
Still going fine - when do mounts need to be replaced?

I have a 1997 with 86,000 miles (138,000KM) and they were replaced this week.
Found sitting at a stop-light, there would be a slight vibration.
FYI, normally you replace the engine/trans mounts at the same time.

If the engine does not pop up left and right, your good.
When the mounts start weeping its time to weep.

The mechanic I go to took a look & confirmed the motor mounts are collapsed.
How many other R-129 owners have replaced motor & transmission mounts?
If not replaced by now ... they would all be collapsed.
Does it really make any difference?
I do not want to continue to put undue stress on drive train - if that is what might be happening.
I do not experience vibrations or noises (that I have not become accustomed to anyway) ... so will replacing mounts at the advanced mileage really do much?
