As I was reading this, I had so many things to say but Glos Guy said it all. I would add however, if you think your recent car choices have posed problems for you, paying £3500 for a Nissan Leaf and saying it’s good news, is just asking for more of the same.
As well as insurance and maintenance, I would imagine the EV will need to be safe and serviced correctly to comply with properties insurance conditions, the original 24 kWh Nissan Leaf when new would achieve 40 – 50 mile range in the winter, with an deteriorating nearer 25/30 in the winter.
There’s some great older cars out there, if you look and not for alot of money. I recently got hold of a immaculate 05 plate Rover 75 V6 with 40k miles, full service history, which would have been a better bet than a leaf.
