Are dart sports mostly gone

Over the decades I have had tons of Dusters, and just 1 Dart Sport ans 1 Demon. Just what came along.

Back in the 80s, 90s.. there were so many B,E body builders. Even hemi cars were not hard to find. I never considered a Duster, until the very late 90s and then they were cheap drivers.
But....I recall ready to spend $$1800-2000 for a 69 340 Dart that needed nothing about 1998, but it was winter in Mo. and the owner let it sit outside one nite and the block cracked!!:BangHead:
