Why does it seem that nobody likes painted trim? The SE came that way and I don't see anyone complaining about that. I just painted my car, and did the upper trim. I'm not ever going back to black on those pieces.
I think you should paint the mirrors too, since the band of black is running along the top of the car, and the mirrors are on the side. But I guess that's more of an up-to-you decision. At the very least, absolutely paint the door handles.
