Yes this is a good price considering the low KM's on it. As long as it's had regular oil changes it should be fine.
Air suspension components can become problematic after the 10 year mark (or earlier) but its not difficult to fix. If you're a real piker you can change to coils - but if you're going to do that you may as well get a different car.
Fuel consumption is probably your biggest issue. Thirsty buggers they are.
