Biggest one with old fords is make sure is not a ringer or been in a really bad smash! HPi check is best thing.

Other problems are just normal things you get with any car really. I would find out when it was last serviced though including belts, gearbox and diff oil replaced, brakes pads and discs and when the brake fluid was last re newed.

Oh and welcome to the magical world of cossie ownership and not forgetting good luck!
