Really the only people who should be concerned about seeing JNC as an abused term are the owners of this website, I would have thought. I'm interested in all sorts of different cars so as a result I'm spread onto all sorts of car forums and a consistent theme is people going to great efforts to try and "officially" determine specific rules on what determines the category a certain sort of car goes into, usually via arbitrary rules that they start having to make weird exceptions and case rules for, until the whole thing becomes a great big mess of people trying to argue a case for whatever for probably fairly insignificant reasons.
Here's an example of what happens. Let's say right, (using this as an example, not a definition!) a JNC is basically not a 90s car, so we set an age limit. You can only call something a JNC if it's pre-1990. Right? We're all agreed. We like 60s swoop, 70s cokebottle, 80s boxes, but not these new-fangled 90s cars.
So we can't have this '92 model Laurel then, even though it seemed people on here were fairly interested in it when I got it and by all intents and purposes is a car from the mid-80s:1992 Nissan Laurel 1800 LPG Taxi

At that point you then say "well, some people just have to lose out" meaning you pointlessly exclude people on a "letter of the law" basis or you start making rules that it applies from when that generation was originally built, which means you'll be having to accept some surprisingly modern cars which were launched just before the turn of the 90s and lasted a long way into there, with some people being irked about it but the rules say it's OK so tough luck - you made your bed, now lie in it.
And you could do rules on what something looks like, but that's a can of worms in itself. Chrome bumpers is a popular one.Mazda 323 Hatchback SP advance information 1979

"Oh, they've got chrome bumpers" "Yeah, but I've got the sports model with the black bumpers" "GET OUT"
Never mind all the 60s painted bumper Kei-car stuff, or the debumpered race cars, or plastic bumpers with large chrome inserts, or plastichrome, or whatever other baffling and weird exceptions to the rule you can make up.
The alternative is that people just drive around and tinker with their cars and not try to worry about it that much, because most people will just think a cool car is a cool car and aren't that bothered about carefully slotting it into some kind of category. I get the impression from the front pages that the site owners are of this mindset.
Let's face it, if something's not really interesting to the people on this forum, it'll be reflected in people not talking about their car and their thread disappearing down the bottom of the page. Relax!
