Car Guy Thing

Car guys naturally know one another. I think it is a gene thing. All you have to say is "nice car" and it is like asking "Are you a car guy or do you just have a cool car?" By their reaction to the "nice car" statement you can instantly tell if that person is a car guy. I say "guy" a lot but I guess it could be a girl too. I only know one car girl though, that is my sister.
