Ford explorer thought of buying is it worth it? 100,000 miles

what yr? make shure is dosnt have coolant and oil mixed. if thats ok then make shure trans shifts ok, are you a do it you self. if so doing brakes youself can save you a little money. if this is a pre 1994 explorer they had there fair share of oil leaks,a.c.problems,some wiring concerns. depending on what year i personnaly like the explorers....sooner or later all ford explorers with need at least some new radius arm bushings,
