Thanks, guys.

Both transmission and engine mount were last changed at 32,000, 7 years ago. Early, yes, but dealer changed it under warranty. I believed they decided to use their "goodwill budget" from Mercedes on my car. Car is now at 101,000. I know I may get some "funny" answers....but is it safe to say, new engine mounts and transmission mounts would not be out of the question? That is to say, will I get some, "Wow, they lasted that long?! What do you expect, buddy?" or "That's ok, they can last that long or longer". Thanks in advance for your input.

P.S. Again, from your infinite wisdom and/or experience (that's where I get my know-how ), what about the center support, i.e., generally accepted life based on mileage or time? Is there only that $11-15 dollar part to change? Is a support bridge different?
