Planned to follow the path blazed by others, such as Darin/metroMPG & jwxr7's, with Geo Metro's(swifts) to at least a consistent 75 mpg(3.1 L/100 km). I do 70% highway driving at 100 km/h,so this may be a tall order according to MetroMPG's website data on speed vs fuel economy, but I like a challenge.
