OT, but is there any other places other than realoem.
Usually they are pretty good at listing seperate superceding PN's.

I'm well aware pricing and certain other things may not be uptodate on ROEM.
But it's weird. Cause I have valid PN for a trim I want to replace....but when I do a particular PN search on a part, I can't even seem to pull it up either under REOM or any of the typical bmw parts sites....
