Is anyone else "touchy" about their Mopar? (long rant...)

The last car show I attended, I took my 73 Dart Sport 340. It was hardly stock (it ran 11.3s in the 1/4), the body was original body color and primer, but the interior had been recently redone. But, at the last engine rebuild, I painted the underhood body color (my personal preference). The most comments I received were in regards to the dual oil filter set up and my fuel pump control system.
The show was a large mall on the east side of Phoenix and was set up with a round robin front row parking (Mopars one week, then Ford, etc.) One week, some guy in his Corvette wanted to park with the Mopars. We explained to him how the cruise parking worked. Instead of moving his car, he stated he would run any Mopar there for a parking spot. I had just arrived and one of my buddies said to him, "What about his Dart?" He scoffed until I went back and brought my car up front. "That's not stock!"
"Well, you never said anything about stock..." He moved.
