Thanks for the info... I'm in a similar situation with a recently purchased 2000 S with less than 30K on the odometer. The car still seems like new...and although I've done a lot of preventative maintenance...I still can't help but think about the issues with the IMS bearing. Luckily, I have found a good local shop that is experienced with the issue. I plan to change the oil frequently, and monitor the filters.
More than likely, I'll wait to do the swap until it's time for a new clutch. That is - unless my nerves get the best of me!
