I have now received 2 emails and a phone call from my Honda dealer with the "We want to buy your Jazz back from you". Their service records report an immaculate low mileage Jazz, but I see no incentive to consider a change to another Mk4 Jazz, pay more for the same. Perhaps a new Mk5 in the pipeline could have changed my mind.
However, when I configure a new Mk4, the price is certainly not competitive, so any Mk5 is likely to be even more expensive, going by motoring trends were new models tend to be more expensive.
I happened to pass by a BYD showroom this week and saw a top of the range Sealion 5 DMi, a mid size family SUV, plug in hybrid, fully loaded with equipment, impressive quality, available on the road for £30k. Smaller alternatives were even cheaper. Considering full EV sub £30k alternatives from Renault, Citroen, Kia and Hyundai, any MK5 Jazz north of £30K is going to be a hard sell for Honda.
