I've received the same indifferent response from almost every 350z owner I cross paths with and a lot of 370z's I run up along with on the road. Older z model owners have a lot of questions about the 370 and seem to like to talk about the cars. Mostly other 350z owners refuse to look over, so I just stare at them as long as I can as I pass by. ha ha.
I would expect indifference from other drivers if we both were driving Maxima's or Altima's. When I'm driving my Astro van I don't wave at other Astro van drivers I see.
However most people buy a Z because it's a cool car, which means the owners have something more in common other than I need a car to drive.
