What makes Mopar owners have such a bond?

I had heard a years back, might have been someone who worked for Carlisle or one of the parts mfgs- Mopar people are different form other makes - Ford, Chevy. He said Mopar folks are into all the Mopars, as opposed to Camaro guys just like Camaros, Mustang guys just like Mustangs, Torino guys just like Torinos, etc. I know there's exceptions to the rule of course. For myself, I've owned A, B and C bodies, liked them all.
