Think lots of people are in this position especially with reference to going full electric. Two thoughts spring to mind:
1) I am satisfied that the Mk4 Jazz is a step change forward from the MK3. I've read and seen a lot of reviews. It's more comfortable, better equipped, faster and more economical. I bought one of the last Mk3s as Honda were throwing lots of inducements around to remove old stock. On reflection I wish I'd waited for the MK4 even though it is more expensive.
2) I've done a lot of dithering about EVs. I've test driven the old Nissan Leaf and spent hours on EV websites and watching You Tube videos published by EV enthusiasts. In the last 3 months, 3 prominent EV early adopters - EV Opinion, EVM and Jonathon Porterfield of Eco cars in Orkney have lambasted the state of the current charging infrastructure. We seem to be a long way from the accessibility of petrol and diesel. An EV would do 90% plus of my trips but about half a dozen would be problematic in the type of EV I can afford.
In short, my next move will be a hybrid.
