I hate car shows, never entered one, but have inadvertently parked near them, or cruise in nights in the process of just driving my car around.
My first issue is with so-called show "officials" trying to tell me where I am to park/what I am to do, as I accidentally drive through the traffic jam the show generates. An enraged self-important popinjay POS gets all huffy because I'm driving through the drive thru to place my order at the restaurant they've taken over, instead of parking where he wants me to. Or when I pointedly ignore their direction to turn off into the parking lot, when in reality I'm just trying to drive by on my way to somewhere else.
Second, when I have the misfortune to park near such a gathering, enduring the comments of people "who had one just like it" and they misidentify the year, or even the make.
My paint is original, and is flaking pretty good now, so there are the comments about putting a "real" paint job on it.
The interior and top are also original, and are in good enough shape to cause certain members of the car community to call b.s. on those, because "everyone knows" the interior/tops on these don't last very long. And "how would I know" unless I asked the original owner. Of course, I AM the original owner, thank you. So bite me.
When I'm driving with Lela, my foxhound/pitbull mix, which is most of the time, I also get the comments about how dumb I am to "allow the dog to ride with me" and mess up that nice interior. Well, since I like Lela more than most people, they can sit and spin.
My Mustang is my daily driver during the summer, so there are also the "you oughta clean the carpet" comments. Anyone who has lived with a black interior car knows how friggin' impossible that is and still actually use the car.
