Are dart sports mostly gone

Just like Dusters of '73 to '76, they used to be everywhere.
They built a lot of both.
Now you don't see them much anymore in alleys and fields.
And not many driving around either.
I collected a few of them years ago and there doesn't seem to be much of a market for the ''beaker'' cars.
P.M. me if you need small items, I just may have them.
But, shipping these days might be expensive...
