Nothing (yet!)
I love this car. It has a nice and aggresive look, it has a great economy, it's easy to handle, Very comfortable for 2 people and 1 kid. It has great stability at high speeds and it is not less neither more than what you need.
Great comments... I'm getting a Suzuki Fun on Monday!!!
I'm a single guy and with the impending energy crisis, a 1 liter engine car is all I need.
