Had a CR-Z sport for a week now. We went to buy a new Jazz and came out with a CR-Z! Why? Hybrid makes a lot of sense (no road tax - better economy etc) but the Jazz hybrid is only available in CVT - we originally had one of these but hated it. We don't really need the load carrying on the Jazz as we also have a Mercedes and a van - so the CR-Z started to make sense.
First impressions of the CR-Z: Economy - slightly better than the Jazz, Performance steering and handling are much better. In short the CR-Z is a 'drivers' car but without the total practicality of the Jazz. I will always have fond memories of our three Jazzes, but I won't miss the 'sticky' steering, the 'flat' top end performance and the 'useless' handbrake.... and that all other road users assume that you are over 80
BTW - the Jazz only had one key - after much head scratching I discovered that once a key chip has been programmed to a car it cannot be rewritten for another car - you have to use a new chip or new key.
