Yep - the November '91 would be impossible! Ooops - it was late. I pulled the receipts from MBZ and it states the motor mounts were replaced, so I'm guessing the transmission mounts were not... So, they are "officially" on the list to be checked. After reading alot of posts, here's a list mounts I've come up with:

Transmission Mount
Engine Mounts -- repalced already! - maybe defective?
Engine Shocks -- applicable to w124/E420?
Rack Dampner -- applicable to w124/E420?

Anything you would add or remove from the list? Thanks, John.
