Something most modern (and expensive cars) don't have because of endless cost cutting on the mechanical side.

No it's because Citroen had super nifty _non-independent_ suspension back then. Pushing the front wheel up would push the rear wheel down making the car feel like it's floating across bumps. Present in various forms on several models in the 70's.

Turns out linked suspension isn't great for handling and road feel at higher speeds. Modern cars are fast and heavy so these systems have fallen out of favor.

The "Frog" (can't remember official name) had a similar system but with hydraulics.

The Citroen 4 had this but with twisting rods instead of springs. You could easily get it up on 3 wheels with spirited cornering.

I wouldn't take the 2CV as an example of suspension that modern cars don't match, but Citroën's later hydropneumatic suspension[1] are indeed unmatched.
