I have an 87 325 (sedan), with the aluminum window trim, and it's pretty beaten up and oxidized. I'm going to polish the daylights out of it just to make sure, but I think it's time to replace it. With black.
The E30 318s I've seen have the black trim, which I imagine would fit just fine, but I've only seen coupe models, and I seriously doubt the rear windows are the same size. If they are, hey, cool, but probably not. I'm pretty sure they sold four-door E30 318s in Europe, but I haven't ever seen any in the states.
Did BMW indeed import 318i sedans to America, and is there any reason switching the trim with a 325 be a stupid idea? I'd also like to get an idea of how difficult this would be to remove, if anyone's ever done it before.
