I bought my Yaris as a commuter and I am so glad I did. I have a little lead foot and get between 32 and 34 MPG in the city. It's fun to drive and easy to manuver in traffic. I drive it everywhere instead of driving my other two vehicles. Best car purchase I've made.
Fuel economy and maneuverable.
Tends to move around some in high winds. Road noise at highway speeds is excessive.
