actually i get about the same mileage except in town and my subaru beats the bonny hands down. Must be my quick take offs and stuff. Considering where I live and stuff it was just a better decision to get something cheaper on gas for the time being. Plus I was wanting to update the bonny and go with something newer. I guarantee i'll be back around with a newer car in less than a year. But for now I still have the old 89 bonny to enjoy. Seems like that car will run forever. It just turned over 239K last week.
