I just did a trip to Minnesota. I rented a Ford Focus 4 door sedan. The other choice was a two door Aveo Sedan (yeach). Not yeach on the Aveo but the two doors. I got 31.6 MPG over two tanks of gas with a mixture of city and highway driving. My own aveo just went from 32-33 down to 28. That means it's time for some TLC (change oil, new air filter, check tires blah blah blah).

Very rarely I get really great numbers meaning 35+.
