I had a 1.2 S A/C today as a loan car whilst my GD was in for a service.
Nothing really much to say next to the pre-facelift cars. I find the restyled bumper fussy but on the whole the Jazz is still a stylish small car. On the road it is very much the same with no noticeable differences so I don't think Honda have made any changes under the skin. Next to the '07 GD model the steering is much better, the handling more pointy but the ride - although less bouncy - picks up more ruts and ridges in the road.
Inside there is really very little changes. The new black-on-red radio displays looks dated but even this low-spec model now has a reach adjustable steering column.
It's all pretty much business as usual as with the pre-facelift cars - more fun than a Vauxhall Corsa but a Mazda2 (and presumably the Ford Fiesta) would whip its backside on the road. However nothing else can touch it for interior space.
