All they say at the Shelby American Collection is that if they catch a CSX 4000 car vintage racing in their group they will quit. It has to be a car produced by AC cars.
Seriously Evan, you would so enjoy this party and the cool cars. You should make plans to be there next year. They are not snobby at all. Very nice people. Very nice cars. Welcoming to everyone. It would probably be over an hour before you said something that offended someone to the point of violence. They are that nice !
