For a 4 cylinder vehicle, the mpg could be better. (How about a 6th gear Scion!?). I average between 24-28, have gotten over 30 at times.
Gas mileage is alright if you stay under 70mph on the interstate/highways. I actually get the best mileage in town

Best that can be said is that fuel economy is average for car of its weight and engine displacement. Automatic transmission only available in 4sp w/OD. A 5 or 6 speed tranny would be better.
