This past summer I re-did the entire upper have of my 2000 BMW e38 in black alcantara. Was not an easy job, especially at the front where the sun visors are and on the sides the grab handles are. Alcantara doesn't stretch easily. The idea of the material not having to be swapped is awesome. I'd rather very much take out the old and install the black headliner and trim WITHOUT having to recover everything like I did in the 7-series.
