Car for college??

I need a car for college and am looking for a little advice. I need something that's good on mileage but not too small (like a two door sunfire) and will last for at least a few years after college. I'm looking mostly at stratuses and impalas but am considering a civic I can get a good deal on. Does anyone know of any other cars that I should look at? And my budget is $5,000.

Thanks
