Nothing.
This vehicle is extremely versatile, has loads of space and comfortable seats.
Ride a bit firm especially at low speeds, but it handles well, no roll to speak of.
Nicely assembled and very well equipped.
I test drove the Jazz, and I think it is great. It is very smooth and refined. However, the build quality of the dashboard put me off. If you try to scrape your finger nails over it, it produces a mark.
I think the best part of the Jazz is its engine. It is smooth, fine and very quiet except for a whine that is acceptable above a certain speed.
