Doesn't sound half bad if it is in good condition. I'd get it checked out by a mechanic first though. We had a lincoln at one time (used) that was an excellent driving car, but the air suspension was a pain. They ride great when they work, but are problematic. Many mechanics don't know how to work on them if something else besides the air shocks/compressor goes bad. We had a nightmare trying to fix them. But as long as it checks out, then I'd say go for it. YOu should be pleased with it.
