This isn't the be all end all manual like Bentley makes (not that they make one for these anyway), but it's good for what it is. Not the most complex of cars, it'll still help you work on them, and you will, they're not getting any younger. I've always tended to get more into from the Haynes manuals over the Chiltons but neither will match a Bentley when put together, if it's offered for your ride.
For basic upkeep/repairs this is about as good as you're going to find but being a Fairmont IS a fox body, you might find something better out there. I can say I've found it to be very useful.
