Toyota Prius C One
The best thing about the car is the gas mileage. If I drive normally, I consistently get 54 MPG. If I am heavy on the gas pedal, that drops to 50-51 MPG. The worst thing about the car is the suspension, it really sucks. I am on the freeway the majority of the time, so I can live with it. But when I am on the street, particularly in areas with poor street maintenance and lots of potholes, its a pretty bad situation. Overall, the mileage more than makes up for the poor suspension. I have seen many people buy much smaller, wider and thicker tires and wheels, and I think the horrid suspension might be the rationale behind that decision, not just the overall cool factor.
