That reminds me of an old joke...
"What's the difference between a BMW and a porcupine?"
"The porcupine has the pricks on the outside!"
Of course, you could substitute any car make/model into that.
But seriously, I don't label owners of any particular car brand or type. People are people, and most car folk tend to get along even if they don't share the same views. I've had lots of people who drove Mustangs and European cars admire and compliment my TTA when I had it. Only a few didn't.
I've known Joe for quite a few years, along with a few other GNX owners, and they're all good guys. The Chicagoland Buick club was and is full of great members. They welcome TTA owners in with open arms. The Pontiac club, eh, not quite as much.
