The airmatic system consists of a compressor (that over time needs rebuild or replacing, as it has a relay gets stuck to the on position, and you can never tell why, and keeps pumping until it breaks), the struts and rear springs have a certain lifespan as common shock absorbers do and in order to change them you have to dismantle half the cars components, and as if all these are not enough, the car has some 3 or 4 accelerometers and other sensors that are probably made from pure 24k gold to justify their price...
I had the misfortune to replace both compressor and all air-matis, because one (the rear) went bad and had a leak, so the compressor was working overtime to build pressure to the system.
Leveling sensors cost at about 150 euros, air valves at about 400, pump 500, struts vary from 400 to 600 depending on make and so on.
My repair was done at an authorized dealer and as I had the extended warranty we split the total cost of 8.500 euros and I paid only for the parts with a 10% discount.
Trust me, stay away...
Of course there are others who will say that they have 100.000 miles on the clock and no problems so far and I am the 20% that had a problem with the car.
But then again, what makes you think that you will be on the 80% side?
