I'm with 'Ivytek' on this one, for the overall package there is nothing to beat the Jazz, every car has its good and bad points, you pays yer money and make your choice.
Re the 'jiggly/harsh ride, my daughter has a 2012 5 series BMW, a car costing more than twice the price on the Jazz, in my view the ride is no better. Anyway, I much prefer this type of ride, to the rock & roll gait of many of the competitors.
Perhaps my only criticism would be the limited choice of tyres and maybe windscreen reflections. Also there should also be a better choice of standard colours, ie, in the UK, Red is the only colour you can have, without paying extra. Other than that I am happy and would certainly buy another one.
