The brand dies, the interest in the brand dies, the aftermarket parts dry up. If you can't see that then you're an idiot. It's happened historically with just about everything that hasn't been produced in ten years. Don't believe it? All you have to do is take a look for yourself.
If you can't see what's good for the hobby, you're an even bigger idiot.
Oh, but that's right, the only thing you care about the hobby is your own car. Hell, you're not even a fan of A-bodies, just your A-body, let alone anything else Chrysler has ever built. Just about every thread your idea is to compare everything to your own car and call everything else junk.
