I personally like the chrome. I have a black VW GLI with the chrome trim; it was deleted from the 2007 or 2008 model year (as were the sweet blue tint windows, unfortunately). I think the chrome trim adds an element of class, and looks really nice set off against the black.
On a BMW, the Hofmeister Kink is more apparent when the chrome trim is there to emphasize the line.
All in all, I'd prefer the chrome. To the poster above who said the 128 won't have it; do we know this for certain yet?
