I have a 1991 Ford Escort Wagon that I picked up for $750 a few years ago. Great gas mileage (30+), very easy to work on, an great at carrying bulky items. It certainly is not easy on the eyes, though. It's a real beater, but it's been mostly very reliable.

Or you could get a small truck. Much better for hauling bulky items. Nissan's or Toyota's from the 90's should be fairly cheap, and readily available.
