I forgot to post this last week:
Last Friday I was driving east on Arapahoe near Parker and I saw an E46 M3. So I pulled up next to it and gave the guy the "whats up" head nod. Just then, an E36 M3 with a chick driving it pulls up on the other side of me and she gives me a big smile and a wave. That was pretty freaking cool. An E46 M3, E92 M3, and and E36 M3 all sitting at a light together by chance.
