I am new to this forum but it seems to be dominated by serial complainers. Headlights, CVT, boot size, boot floor, proximity alarms, etc, etc. I accept that the infotainment is a bit glich prone. There have been calls for Consumer rights, Watchdog, writing to Honda and it's CEO etc. Didn't people research their purchace before parting with their hard earned cash? There is a headlight survey somewhere on this site with 16 don't likes. As far as I can work out there are 8,766 Mk3 Jasses registered in the UK. There must be a vast majority of totally satisfied owners.
Before I bought my Jazz, over about three months I did several test drives, and was given a demonstrator for an afternoon and I read the UK owners manual. In the Brochure on page three it states that the car has been completely re-engineered from top to bottom. As I had not owned a Jazz before I did not make the mistake of comparing it to previous models, it is obviously a complete redesign.
The time to find the things you don't like about a car is before you buy it not after.
