I have to say that a black car with black alloys and polished edges looks amazing on most AMG's. You get to to appreciate the massive calipers behind aswell. I put blk rims on my CLS55 which was black and my A45, also in blk again had blk alloys. Both looked spot on in my opinion.
This is a tricky and by virtue of the fact that the matter is being discussed must mean there is some general uncertainty on the point.
I am uncertain too and have considered getting some anthracite/silver wheels on my E class but, the wife says the black wheels are great and suit the car. So, decision made then However, for her to say this came as a big surprise. I think this debate will run and run and we will never see a consensus, which is probably a good thing; life would be boring if we all liked the same thing surely?
Black on black is a personal thing, I love it, whereas some do not. You'll find that those who deride others tastes are insecure about their own choices.
Here's some of my previous "black on black":
