I know a few Z owners personally that are some of the coolest/humble people. I know that not everyone is a douchey owner. I think that I'm pretty approachable and would be able to strike up a conversation with other enthusiasts around me, but I guess some hold to themselves. I wish I got some pics of the faces these people make though, if facial expressions could be translated it's almost like "Why are you talking to me?" and then "Want to see how fast I can go?" but oh well Nismo89 is right, to each their own.
Not saying you gotta be friends with everyone but it's just weird that this has happened on more than a couple occasions
