As I recall with these darn things, it's a pump powered hydro suspension system fitted with seven gas spheres at various points around the car. If your buying one the key is to pull a sample of the fluid in a clear test tube and hold against a newspaper. If you can read the text through the fluid then it's a good cert that the car has been looked after. The spheres can be trouble to obtain, they have a limited service life, and the pumps are prone to start making clicking noises more often than not prior to failure.
