A-bodies were and are the bottom of build quality for all of Chrysler back in the day. So I would be shocked if value actually rivals B-bodies. E-bodies have gone nuts. And it's because of this. And the surge of interests in 68-70 Charger that has dragged A-bodies up with them?
The usual suspects with Chevy has plateau. If anything Chevelles may have dropped a bit. (Just due to so many) Camaros too. As GM fans start looking at other platforms. Like GTO that is still going strong? As well as other Pontiac models. I suspect Olds will pickup? They seem to always be in 3rd place in the GM world?
It will be interesting in the post pandemic of the next couple years? A lot of home restoration car projects should reduce as so many venture out. (Possibly abandoned, thus opportunity?) But we'll have to see.
