I traded my 2005 Corolla for the Yaris 2 door hatchback w/power package. My insurance decrease, my payment dropped significantly, and I get lots of oohs and ahhs from friends and colleagues. The car is extremely economical. I'm getting a tad under 34 mpg around town: I have yet to do the highway, longer drive scenario. It is roomier than the Corolla was.... has more safety features, and is just fun to drive. It's a great second car backed by Toyota reliability!
Gasoline economy,interior room, and styling.
Improve the interior sound dampening. A better radio would be nice too.
