MV2s - they look great on a black coupe, there are some fine examples on this forum. 108s do look a bit dated, although they are real overkill when refurbished in black.
I had Mv2's on my black coupe when i bought it http://i1164.photobucket.com/albums/q576/beaucostil/aug118_zps5682ab02.jpg
Got rid as i had the same wheels on previous 5 series & wanted a change plus they are a pig to clean :x
The 108's can date the car but some folks have 2 toned them & that gives a nice look , think "adamski" has them that way & they look great
