The future may be EV but much of the world is no where near having the charging infrastructure to make it viable . Japan still has the option of a petrol only version of the Jazz/Fit mk 4 while Europe can only have Hybrid.
I suspect Honda will continue making conventional versions of Jazz, civics , etc for a good few years yet for some markets .And rather than trying to squeeze Full EV into older chassis the next move may be petrol versions of the new EV range.
But Europe may not get the option of older designs, or petrol versions of new designs.Only Asia,Africa etc. The Jazz might be replaced by the nearest EV equivalent, like it or lump it. In which case the last Hybrid Jazz has advantages for those not yet able, or willing ,to go fully electric, and might be sought after.
Whats available in the uk may also be dictated by whats still made for the right hand drive Japanese market. Honda have pretty much given up trying to compete with Toyota and Suzuki in India,so any 'heritage' designs still produced for developing countries might only be available in left hand drive.
