I had planned to wait for this model but am extremely glad I did not. I would have been very disappointed.
I like more glass and the bigger boot of the current model which was what ultimately swayed the purchase.
It sounds to me that the MK3 Jazz is rather modelled on a scaled down 7th generation Civic.
We had, until recently, a 7th generation Civic with large rear leg room (advertised as equal to a Mercedes S Class) but a relatively modest boot which for me was a wee bit annoying as we only ever really have, at most, two in the car. I rejected lots of other cars (Toyota/ Nissan/ Citroen/ Kia etc.) because the windows were too small, the interiors too gloomy and the boot too small.
Each to their own...........
