I'm now on my 4th Jazz, all of them EX models, the first was an I-shift, followed by 3 CVT models.
As others have said It's nice to have all the gizmos, for me the climate control and rear view camera were attractive options to have.
However the bottom of the range will still get you from A to B, in much the same comfort, so it all comes down money, you pays yer money and makes yer choice
