There are quite a few TSBs for this car (you can search them on this forum) and I would ask the present owner if they have a any records as to what TSBs (and recalls if any) have been performed so far so you have an idea what might be waiting for you down the road. Remember, once your car is off warranty, it is very difficult to have the TSBs performed free of charge. Come to think of it (if you ask nicely), ford should be able to tell which updates have been performed by them.
