Smaller car? In my neck of the woods, your car would be worth $2-3000 if it isn't too rusty. Probably it would be tough to beat your car for reliability though, I wouldn't bet on Geo Metro over a Camry but it would use less gas although maybe your leg wouldn't like pumping a clutch?
If you can accurately keep track of your total mileage on your GPS, try accelerating abit faster for a tank of gas, your engine and torque converter might be more efficient at 1/3 throttle than 1/6 for example. Gives a shorter pulse with a longer glide.
