a 660cc car is v sluggish. It lags badly, to get anything good outta it you need to be harsh with the car i.s aggressive with your right foot, which means a poor economy, drove a 660cc mira es and found it too slow for even daily purpose journeys while being light with the throttle moreover vitz has a way better drive never drove a 1.3l but just hours back drove a 2008 1.0l auto and it was excellent!
