Very good advice!It might be an idea to have a mechanic assess what needs to be done to get the car into reasonable, and safe, operating condition.
No offence but, if you could not see all these problems before the purchase it's time to admit you could use some help and get professional advice. Car inspections usually run $150 (US) or so. Once you have a real list you could probably do a lot of the work yourself. If you don't get some eyes on help you'll find yourself throwing more money at the car than you have and not getting a better car.
Next time I advise getting the car checked out before you buy. Of course sometimes the price is right so you take it and worry about issues later.
