So far as I know, it's more like a hydraulic bottle jack, I'm not
sure if it pumps air or fluid as the thing flexes. I believe its

That's different. The leveling device was, IIRC, always
called a 'compensator'. Though it was _a_ hydropneumatic
levelling device, it was not _the_ hld.

the general feeling is that the springs work for sixes but not for eights.

I couldn't disagree more. I replaced the rear spring kit with an OEM used
compensator and this eliminated a lot of harshness in how the car takes
bumpy roads, esp. in the rear.

Perhaps. I noticed the differnece immediately in my 280SE 3.5. I can't
recall whether my W108 280SE sedan had the spring or the compensator.

They were never cheap but occasionally someone is selling a good used one on
ebay.

I'm guessing suspension movement pumps it up.

As it bounces up and down it moves the pump piston. Like I said,
elegant. The only way the newer system was superior was that it
would pump up just sitting there, the older one had to be driven.

Wasn't the OEM (someone like BOGE) pressured to stop selling them so
MB could mark them up more? This far out there can't possibly be any
IP issues but then again, it would be a small market in any case.
A former '67 230s (110 or 111) had a bad one.
