There is a car wash here in town where all the mercedes and bmw people go. Its $25 dollars and they hand wash and detail your car. It sees a lot of very expensive cars, after i dropped my car off and went inside to the deli i had 5-6 guys standing around me asking about it. I also had the wash attendant kid ask me about it.
Mostly i just get people that stare, or they point when they see the wing pop up on the freeway.
I'm in Oregon though, for some reason xfires are rare here.
