one thing ive had on the escort vans before are the clutch pawl and ratchet goes sometimes so i would check that, unless its the manual adjuster on the clutch pedal, in which case no need to worry..
i had a fiesta courier (shares the same engine) and had a lifter break up which resulted in a new engine as it wedged between the cam and stripped the cambelt, so i guess just listen out for any major engine rattles...
wishbone bushes, especially the rear bush on the front wishbone tend to split out, this will cause tyre wear and probable knocking on suspension...
only other thing which most fords are renound for is rust...
not to scare you of course hope this helps
