Here is SW Florida, "Bimmers" are as common as Camarys. Mostly 3 series (tons of them), with a fair amount of 7's. I imagine the heavy population of 3's is due to their low starting price (virtually the same as a 2 series car). Most figure why get a 2 when I can get a 3.
I see a number of the older 1's running around (mostly verts), but have yet to see a 2 series of any kind. M's are also rare and when I happen to see one, I leave a smidgen of drool on my shirt.
