I have seen 2 E9Xs in the last year around my parts: 1 AW E90, 1 AW E93. I'm sure there are more, but I just don't see them. I'm pretty damn sure I'll be one of only(if not the only) a few LMB E9x. I would actually be willing to be that I'm the only one within a 25 mile radius of my house.
E46s I do see more often. Always a treat to see one!
