There are all kinds out there, in all brands. Seems like in the "old days" everyone was just having fun and happy to see another Muscle Car, regardless of brand preference or personal favorite.
Now, it seems like people are just angry all over. If you are quicker away from a light, have a better detail job on the paint or even throw a friendly rev, people take it like a slap in the face and react like you have personally disrespected them.
It's all good. I, for one, take it on a case by case basis and will gladly give a thumbs up to a great looking / sounding / performing vehicle, regardless of what it is.
