When I was about 11 or so, my folks got an '81 Dodge Omni. That thing somehow slipped out of the factory with an experimental carb. It was rated for like 40 mpg in town and 45 or so on the highway (1.6L/4-speed manual). We would regularly get around 70 in town, and on the highway, we'd get upwards of 110 mpg. No kidding, at the time we were living in Huntsville, AL, and we could make it from there to Granby, MO (outside of Joplin) on a single tank of gas with plenty left over. That's a 600+ mile trip each way.
