one of the greatest cars... ever had several face lifts. had a complex suspension. it had power steering, disc brakes, in 1955! built from 1955-1975 https://en.wikipedia.org/wiki/Citroën_DS
I prefer US luxury cars of the day. Many of them had air suspension (even better than hydro - none of that fluid stuff), but coupled it with better performance, equipment and actual automatics.
