For $2000 I'd stick with an older Japanese vehicle with as few power features as possible. Power windows, locks, seats, etc. tend to go first.
I'd recommend an older Civic, Accord, Camry, Corolla, or Tercel. Most older domestic small cars aren't as reliable and it's hard to beat an older Japanese 4-cylinder in terms of reliability.
Of course every rule has an exception. The Dodge Aries and/or Plymouth Reliant (k-car) is perfect. They're cheap to buy and maintain.
Good Luck.
