Welcome! Both the normal Jazz and the Crosstar are good choices. We like the front and the wheels of the Crosstar more, so that’s why we chose it.
In terms of driving: the Crosstar has a bit higher driving position, but only an inch or so. You do not notice it much. Both are pleasant to drive; Crosstar seems a tiny bit firmer.
After purchase we also found out that the Crosstar has a very good sound system!
Enjoy!
