Larry I did what you want to do. Bought a $500 car, spent about $150 on it and got double the mileage of the Jeep. At the time I was commuting from Beaverton to Woodburn and even with the added cost of insurance I made up the difference in fuel consumption in a few months. I just sold the car for $500 so in the end it cost me almost nothing. I say do it right and it'll work out for you.
