My dealership candidly told me that the Jazz (which I assume includes the Crosstar ) is the mainstay of their business. I think he said they sell about 100 Jazz a month , greatly enhanced by Motability scheme sales. This figure might only have been for the two peak months when registration numbers change. He said that all other Honda models combined only add a few sales per year. These alone would not sustain their Honda franchise.
So if Honda stopped selling the Jazz in the UK (or only a full EV version) , or the recent Government proposals to reduce Motability eligibility becomes even more restrictive, Honda may exit the UK market completely. (Like Mitsubishi did, although I read a rumours they are thinking of returning.) Honda might have abandoned UK/Ireland sales before this if Japan were not also Right Hand Drive.
I had initially planned to keep my 2021 Jazz for 5 years ,but was putting quite a few miles on it. I decided to replace it in 2024 , partly in the hope that it will then be suitable for further 3 -5 years by which time I will be in a better position to decide on the continued future of Honda in the UK, and whether any new M5 Jazz, or similar that may have emerged still appeals to my changing needs and budget.
