Are dart sports mostly gone

Well, it looks like I was into Dart Sports before Dart Sports were cool!
I actually prefer the looks of a Dart Sport over a Duster.
I have a '74 Dart Sport 360 4 speed car (rough but restorable), a '75 Dart Sport 360 column automatic (a little rough around the edges), and 4 other Dart Sport parts cars of various years, and 5 '71 to '75 Dusters... 2 projects and 3 for parts.
That doesn't include the Valiant and Dart 4 door parts cars with a smattering of '68 to '76 4 door Dart and Valiant parts cars.
I even have a '74 Dart Sport slant 6 Hang 10 project car which is complete and restorable.
And lots of spare parts.
And nobody wants them...
Yeah, I'm sick!
