Eh, I might be a dick. Car meets in my neck of the woods is alright. I don't really fit in with any crowd so I don't go unless someone specifically invites me.
A while back, I went to a cars and coffee and rode out with a bunch of mopar guys, one of them had a Demon. As usual, I'm the youngest one and these guys were old enough to be my dad or grandpa. These guys ONLY talk mopar and about the trophies they won, love to talk politics, and tried to sell me stickers, vinyl, hood props, etc. Not feeling it, so I just walked around looking at other cars, etc.
The ricer guys...yea, they pull up vaping a huge cloud and usually blasting EDM/Dubstep with a rattle can exhaust. Don't even bother with them.
Tuner guys...I'm a domestic guy so they don't talk to me.
Exotic guys...snobby, usually only discuss golfing, wine, or the next car to add to their list of Porsches and Ferraris. I'm not worthy.
Mustang and Camaro guys, they rev before entering a show or meet to let you know they're here. Usually a big group of them and they're usually obnoxious. Oh, they almost always gun it out of a car meet.
Then again, it could just be me. I enjoy talking about cars, but most car guys I talk to are all about their car being better than yours. Even if they're comparing their BRZ to your Hellcat
