Not that I don't like Mazda but they don't really don't get awesome mileage in my experience. Sometimes they put short final drive ratios in to make the car sportier but it hurts mileage a bit.
You might find an early Echo sedan for $5k, that should pretty much trump anything else for mileage and passenger space. You would be hard pressed to tell the difference between the echo and the corolla if you were blind folded.
