A good reason to get an Aveo (or any car, I suppose) is if it's a screaming deal and in decent shape.
Otherwise, I'd look for something more efficient, personally.
EPA ratings for the '08 Aveo 5-speed is 24 City, 27 Combined, 34 Highway.
Not horrible, but it doesn't even qualify for our
35+ mpg highway $1500 beater list.
