I can shave off of your list:
No Backup camera
No ABS
No Airbags
No electronic assist cameras, sensors, braking, lane assist,
No network connectivity
No Seat warmers
No CVT, or electronic transmission (Manual is fine)
No sun/moon roof
I know, it sounds like I want a covered wagon with a/c. At this point I would happily buy most any 70's or 80's vehicle if they were new at this point. To me they were equipped with enough, but not too much.
Compared to modern vehicles it is very easy to work on the 1984 El Camino in my signature.
