....a mk2 golf gti?

just some kinda list on things to check, bad rust parts etc.
also what year comes with what. . want power steering but not fussed about the rest.
Ok 'ish to buy a cheap one if needs a little work, , but what work is a little work and what little work as some may say i should keep away from?
any kinda help would be awesome as don't want to be stuck with one with a bunch of problems as it will be my daily car.
