In this area (Boston) it seems like a landslide. Since I ordered my car, late April 99, I have only seen 1 e46 in fern green, 1 in Orient Blue, and probably a couple or 3 in Steel blue (including my own), white, & black. I have never seen an e46 in any other color.
Other model BMW's appear here in various colors, including the bright chromatic colors. I was wondering what the e46 color choice buy rates were elsewhere.
