I would like to do mine too, but I have iDrive and can't figure out how to remove the center console trim. My buddy has done it on his non iDrive and it looked a lot better and just took awhile on the inner curvy parts. Sounds like everything else is pretty straight forward.
Let me know how it goes and what type/color you end up buying. If there's plenty extras, I may buy the rest off of you.
