I changed the engine mounts on Madeline (1981 300D) last night and I am amazed at the overall difference in the car. I have never needed to replace engine mounts before. The old mounts did not necessarily look bad, but what a difference. Less vibration and clatter and no big 'clunk' sound when then engine stops. Well, worth the money and time to install. It feels like an entirely different car. There is a DIY thread for this and I added a few comments.

The next tasks are transmission fluid/filter change, power steering pump change, and rear door checks. Need to check my list because I know that there is more.
