I was there from about 6:30 to 7:15 (or right about the time it started to rain on my extremely clean car). The only other Bimmer I saw there was an E36 M3. And there was one nice GT-R (with some ricey decals all over it), a few corvettes, some old Chevelles/El Caminos, and some mustangs.
But the local Chevy Cobalt group brought their "A" game.
Maybe the weather will be better next week!
