Why does BMW put the all black "Shadow Line Trim" around the windows only on the 323 and not on the 328? The 328 has a bright chrome trim running around the windows, which makes the car look... older. I have asked parts and they say I can remove the chrome trim and replace with the 323 all black for around $300 in parts costs. This is just weird -- the 528 sport has the Shadow Line and it looks great. Any ideas?
