Just read the report and the hybrid was chosen to represent Honda. Two of the downsides expensive (well it's a hybrid), hard to find (well it's a hybrid so there are limited numbers as most Honda owners are happy to keep them)!
It strikes me that in the UK Honda Jazz owners are people that have tried the rest and now want want to stick with what they have discovered as the best! The jazz isn't perfect but to get to your destination it nearly is! Mainly older drivers because we have become more discerning and less interested in how "Kewl" the car looks! Even the report has to acknowledge the reliability of the model. (I washed mine Sunday and it's lovely and shiny again!).
Unfortunately these reviewers drive a car for a couple of hours and believe they are experts and sadly their reviews much influence so many people. From the words in the review about "Space", Reliability" and "cabin controls", noise I know has been mentioned though I don't find an issue with it i'm just astonished the Jazz came behind a Fiat! I had a Fiat as a loan car from a Nissan dealer when my Note was being serviced... I have never driven anything so bad in my life and I have had some dogs in the past. Performance was appalling as was space. I swore then I would never drive one again and I haven't and now it comes out rated higher than the Jazz. Sorry the world is now officially BONKERS!
