This about a 1992 740 (last year) so it's really a 940... NA, wagon, 200K, and owned by me for the last 15 or so years. This car is great (still R12 A/C in good nick, all else working, etc.) and I have done a lot to it while owning it so I know it well and it is in top shape except for a vibration which I attributed to a need of motor mounts which had never been replaced.

So I replaced both mounts with some new old stock I had laying around, well, a long time and not OEM. This changed nothing--the feel is like when a car is needing motor mounts, except, well, the change did nothing to remedy the feel! Now, it's not my imagination since I own three more of these beauties and they don't have that annoying vibration! Jacking the engine does not seem to have effect, otherwise I'd be inclined to suspect my new old stock mounts of being subpar. Any ideas would be greatly appreciated!
