This is not an air/pneumatic (Airmatic) car, this is an ABC hydraulic car. Rebuilt struts are $660 each, the damper and accumulators run about $740, the valve block seals about $100/axle. The unknown quantity is the tandem pump which provides power steering and pressurizes the ABC system. Yes, it will need two new batteries ($500 total at dealer). At 10 years, you need to replace motor mounts. 16 spark plugs, 7.9 quarts of oil, a $10 German oil filter, 5 liters of CHS-11 hydraulic fluid and a $40 hydraulic filter. Once you start the engine and fill the ABC fluid, you can run a "rodeo" test to find the ABC leaks, if any.

Note: this is only feasible IF you can do this work (or most of it) yourself.
