The 220 S-Class was available with the optional Active Body Control suspension. The ABC system is completely hydraulic, and shares no parts with the Air-Matic system. It has it's own issues though, and can be just as expensive to own as the Air-Matic system.

Another problem 220's are famous for are clogged water drains at the fresh air intake. All the water that runs down the windshield will end up in the interior if this drain is clogged. It's easy to prevent though. A quick visual inspection is all it takes to avert disaster. I don't see it come up much on this Forum, but I see it all the time on the job.
