The fit is an American honda car. The Jazz is Japanese. The Jazz is a much better vehicle than the fit. Jazz comes with sun roof, a nicer back hatch door, Side view mirrors with signal lights, better suspension, original alarm, better paint job. The fit has none of the before mentioned, it's tank is too small for the engine and the engine is weak.
Fuel Economy show the fit averages 31 mpg. So my good friend the fit is a cheap replica of the Jazz. If you have a Jazz your car is 100 times better then mine.
