In addition to the ordinary used car items, pay close attention to how well the car is assembled ,Notice if it appears that the builder took time and effort to fit and finish things properly or if things were thrown together in a sloppy manner. If you enjoy reworking things, you may get a good deal in a car that someone has got tired of working on, if not you may want to look for something ready to drive.Bear in mind that these cars have their little quirks but there is a lot of enjoyment in them as well.
Be sure that the car has a proper title!!!!!!!!! Each state has their own rules and you don’t want to buy something you cannot legally drive.
I don’t know where you are located but there are three Ford based cars on the internet now. Best of luck with your search.
