Here in NZ 2015 Jazz is being launched. TV adverts show new shape and 'jazzy' bright colours. That's all. And they do offer bright colours out here, some I very much like. But why oh why would I buy a Jazz over any other?! Lots of competitors have striking exterior design and could offer bright colours, too.
It'll be interesting to see if Honda follow up with ads majoring on Jazz's point of difference - extreme functionality, versatility and interior space for its footprint. For now, I despair. Driving a Mk 1 Ford Focus just now, I'm reminded of the clever Jazz every time I need to load the rear to full luggage capacity: I have to remove the rear headrests, shuffle both front seats forward to make space, then collapse the rear seats, shuffle front seats back to 'easy entry' position. What a hassle! I could load all the luggage in the time it takes to do that... Then it's a repeat of the hassle to reinstate the rear for passengers. By comparison, the Jazz is just one button, drop. Other button, drop. All done ready to load.
The back seat space for passengers is not as roomy as Jazz, either.
By comparison the interior of the Jazz is so well designed and engineered... While it's interior space advantage is due to the unique - to Jazz and Civic - central (safer, too) location of its fuel tank. And no competitor can easily match it.
