It's based on the Taurus, with a different engine, sheetmetal, and interior.
The Continental has air suspension at all four corners (my 1997 Town Car only has air suspension in the back) and these are wear & tear parts that probably need to be replaced on the car. At 47k miles, it's probably on the original air springs, also.
You want to see the car after it has been sitting overnight and look at the ride height - if it doesn't loose any height when it's left to sit for a night or so, you can probably keep driving on the air springs in the car. If the ride is noticeable lower after the car has been sitting overnight, then you need to replace the air springs sooner rather than later, or else you'll be looking at a burned out air compressor.
I replaced my air springs with Arnott parts, they enjoy a pretty good rep in the lincoln community (yes, there is a lincoln community), and they are way cheaper than motorcraft parts.
I don't really know much else about the continental. Honestly, I much prefer the Town Car to the Continental, but I've heard really good things about how Continentals ride.
So my advice is inquire about the air suspension. If it's on original parts you are looking at an expensive repair on that car in the near future.
