the door a jar problem. shoot some WD40 into the hinge so the lights switch will push in.
the vacuum breathe tube on the rear axle. make sure its on there or it makes some weird noise in the axle. (does anyone know where it goes to. it goes into the frame and from there idk.) mine came off right at the nipple on the axle. so its on there with a little super glue and electrical tape.
window actuators in the front. (still have yet to fix mine.) as for the hose that was the latest cop to go out. coolant dripped on mine. idk how ford fixed the hose but its the same one.

my door ajar problem went away not by wd40 not by new sensors but rather a shorted wire. fords are notorious for that because wires dont like to bend and everythime you open your door it just makes it worse and worse because of that loom of wires going from the door to the car

Check for water spots under the dash to see if it has the infamous windsheild leak!

Make sure to check the rear lower trailing arms for rust issues.

Had #4 fixed, I hear it's a very common problem & they usually all start going out 1 by one if you don't get em all fixed at the same times. Very costly, about $200 to replace one, that's why I opted in to replacing em one at a time.

Check the upper trailing arms too, mine were worse than the lowers. I have a pic that I can dig up and post.

It's been said, but here's my list:
Rust - Bottom of door seams, rear trailing arms, radiator support, quarter panel fenders
Front Sway Bar Linkage - often goes 'missing' (rusts away?)
Upper & Lower Ball Joints - Front suspension wears out quickly, most people don't replace before selling
Exhaust Manifold Leak - due to warped manifold and/or broken studs; pretty common

The awful gas mileage

make sure it has the better of the two transmissions the 4r100, I forget the door code for it.
Trans Code: E

Taking a code reader with you is a good choice. Had to replace the DPFE sensor and the vacuum line to the evac solenoid was melted against the egr valve. Easy and cheap fixes, improved gas mileage too.
