2001 Ford Focus SE with 144,XXX miles.
I go back and forth to college a lot, and I average between 26-35mpg on the trip TO college, and usually about 40mpg on the way home. My record for best gas mileage is 47mpg, and that was because i was economical and drafted semi all the way back.
I go to college about 3-4 hours from home, so the fuel economy is pretty reasonable. However, i drive like my father, and tend to "put the pedal to the medal" a lot. It doesn't have a huge effect, but obviously it does go down some.
