If you're not making a snap decision, then consider an older sports touring car. They tend to have all the amenities (unlike your typical Civic/Escort/Taurus), and also drive and handle well. Any car in this price range is going to have some warts, so you might as well have a super nice interior and power everything to go along with that leaking head gasket.
I bought a 1990 Mazda Rx-7 convertible for $4500 (4850 with taxes/license) about 6 months ago. It's wart? Salvage title - but the rebuild was done correctly, the frame is straight, and the engine had 57000 original miles on it. Of course it is sporty as hell, has leather and every convenience conceivable, and looks great (new paint from after the wreck!)
A coworker was looking for a BMW z-3. So he built a relationship with a BMW only used car dealer, got his credit and money situation in order ahead of time, and this guy is custom buying him a car at auction for $500 above the auction price. You could do that and probably get a $7 or $8 K car for $5, too. Something to think about.
