Nothing.
After 30 years with Toyota and a slight disappointment with the Yaris (a second car) I am overwhelmed by everything the Jazz has to offer.
The engine needs to be worked in 2nd to top gear if brisk acceleration is required.
I read many reports citing harsh rear suspension, Honda must have addressed this problem in later models.
The fit and finish are excellent, it's the first car I have ever had where my wife can close door first & every time.
I consider the 1.2 S model good value for money and it's £1900 cheaper than the 1.4. with only 6 bhp between them.
The car is quiet at motorway speeds and cruises happily at the legal limit at 3100 rpm.
The electric power steering takes a little time to get used to.
Internal dimentions are excellent (I am 6 foot). The arrangements of the seating are versatile and are easily operated.
This report is following on from my initial comments when the car was new.
I have now had the car for 11 months, the only fault was a loose bracket that rattled on rough roads. It was a bracket that holds the locking mechanism on the fuel filler cap.
The fault was corrected first time and, of course I was supplied with a courtesy car for the half day.
I really can't fault the car. I have owned 15 new cars most of them being Toyota's so I'm quite fussy when it comes to buying a new car. It's the only car I've had that attains the MPG that the manufacturer claims, over 10,500 miles it has averaged 51.26 mpg, Honda claims 51.4 how close can you get. A big deciding factor was that the Jazz is built in Japan. Well done Honda!
