I just read all of these pages describing how people act toward your cars. Wow! See, I live in a small town in North Carolina and my Z is my DD. Prior to this I had a '07 350Z too and I have NEVER had ANY experience EVEN REMOTELY similar to what you guys are describing. I get nothing but complements.
BTW, when I'm not driving the Z... I AM THE REDNECK IN THE BIG DODGE 4WD PICKUP, but I would never hassle anybody because of what they drive.
I guess people are just nice here.
