Yeah, I'd say sedans are now rare in the US. In the 70s and 80s they weren't, but in the past two years maybe six runners have been advertised. I haven't seen one driving on the street in over a year. Sales figures were:

Coupes 89k
Sedans 44k

On the other hand, people bought multiple times more Ford Pintos and Chevrolet Vegas, and I'd reckon there are even less of those around. The 1200 wasn't quite so disposable or apt to rust.
