I have owned a black film MP and a black M240 in the past. At present, I own a black chrome M4-P and a Safari set M-P. I have never not liked the appearance of any of these cameras.
I have never owned a chrome and black M body, but would like to; I like the classic old school look of these cameras.
I am hoping that before too many more years pass, a chrome and black M3, M4-P or M5 will join my small Leica family.
All of the production M cameras are beautiful, regardless of their finish, as are the Safari cameras. It takes a hell of a lot of effort to actually make an M camera ugly, but Hermes managed to do just that with the orange leather M7. I have seen photos of some ala carte M cameras that IMHO were ugly - black paint with red leather, and black paint with green leather. Bluck...
