Ford bronco problems help please?

i bought a ford bronco yestarday afternoon and the guy told me it had 15k on the and 95k on the engine the milege shows 95k i got about a quarter of a mile from the guys house if that before it shut off on me and when you get on it, it will make a rattling noise.. so after only driving that short of a distance and it shutting off it leaked about a half gallon i let it sit for about a hour the battery was dead so i went and spent money on that and it fired right up it sounds nice when runing but it will overheat and shut off it did that about 3 times only going about 5 miles.. i spent all my money on it.. and i cant belive that guy just took advantage of a kid like that.. he ovioucly knew all these problems as i drove off.. anyways i put water in it and it instatly leaks out from underneath the car it looks like theres a hole rigth above the starter that is leaking from and its leaking from the drivers side to right above all the junk in there but i cant see where its coming from on that side.. any ideas on what a young broke kid like myself can do to fix this thing??? PLEASEE!! whats wrong with it! I bought it for my little brothers cause they wanted me to get a bronco and now we cant even go camping or do anything and im completly broke!
