Some people at Car shows

Everybody always tell you about how they "had one of those back in the day". They also get all worked up over $2 trophies.
Last week I'm at a show in North Jersey when a guy next to me says how much he likes my '70 Roadrunner, 2 minutes later I'm sitting down and I overhear him telling a guy how he knows my car and how it has the wrong engine, and is the wrong color. FU dirtbag.
