Rory, I'm now living in NZ.
I understand that (at least for now) the Mugen, RS etc. designations are simply sheep in wolf's clothing. However, I've read at least one journalist saying that, if there is 'sufficient interest', Honda will introduce a properly 'sporting' Jazz here. Mind you, I'll believe it when I see it...
Spotted brightly coloured new Jazz's outside a dealer a few weeks ago... went and 'kicked the tyres', and talked to the proactive, enthusiastic salesman. I didn't have time for the offered test-drive but truly impressive back seat accommodation was viewed through the window.
Exterior styling... in the metal? I'd say Honda are trying very hard with that - and colours - to attract a more youthful market. To my eye, the car looks much more 'premium' (inside and out) than my beloved GE model I sold leaving the UK.
