Before buying Jazz with CVT, have one for a test drive to make sure the coming users are happy with the transmission.
If I hadn't specifically wanted 1,5 litre engine, I would have ended up to base model. The reasons are same as Toptek mentioned, added with the radio having a proper knob for volume control. And the integrated Navi on Jazz isn't the fanciest one, so I would keep using my smartphone for navigation.
