I am 16 and recently got my 1992 Mustang LX convertible in PERFECT condition (it never left its garage other than for short trips) for $7,000. It managed to have 90,000 miles on it, but runs seamlessly. All I have had to do to it so far is fill the power steering fluid.
I would think, knowing this, that you could find a late-80s or early-90s mustang in your price range. Keep in mind, the interior might not be as well kept as you would like, but its a car! I was told to look at V8s because they last longer. Since you will be buying a car that has had a good 60,000+ miles on it, that is probably what you should do to. Hope this was of some assistance. Good luck, and you wont be disappointed!!!
