There is no other car (that I've found) that has the combination of fuel efficiency, excellent braking/handling, subcompact size, safety features, Toyota-like reliability, amazing design quality (interior and exterior), and low price. This car has been *very* fun to drive and show off.
The standard and customizable options are second to none. Its fuel economy is great. The auxilliary stereo input jack should be on every car considering the amount of MP3 players and laptops out there today! Also, I absolutely love the way the car handles and brakes.
Two things: the automatic (that's all I've driven) performance is not the best. There should be more performance options available to increase HP. Also, a sunroof or moonroof option would be great. But those are the only improvements I can think of!
