Gas mileage not what was promised. I'm only getting 22.3 MPG mostly city with some highway. My old 6 cyl Mercedes got similar! The dash board rattles, sounds like there's a hornet in the car. Lots of blind spots, the rear window is like a porthole; the wide front struts and bulky side mirrors completely obscure pedestrians in crosswalks and vehicles approaching on the right. Visibility is so poor, I don't think I'll be keeping the car. Wish I'd gotten the Honda Fit. Too bad, Scion.
The car is cute. I like the styling, interior features and details like the radio controls on the steering wheel. Plenty of leg room, rear seats flatten to allow lots of storage; seats are comfortable.
Minimize obstructions to driver's visual fields. Widen rear window; add small triangle-shaped windows in front of the side view mirrors.
