Without it getting personal you live in a different world to me, the same applies to a car costing £18K it might be 'cheap' to you but it isn't to me & is still WAY beyond what I would be comfortable paying for a car which spends most of it's life not doing anything.
A used Nissan Leaf was down to just £4K a few years ago, but have now people realised how cheap they are to own longterm. Fuel costs of 2p/mile, no servicing costs apart from brake fluid change very few years, £0VED, and now they are APPRECIATING!! If you buy one, apart from insurance + MOT the other upkeep costs really are pennies.
The biggest problems with EVs is price, and that because they are so new, but even a new Fiesta is £16K a new EV at £18-19K is not much more of a premium given their cheap longerm costs.
I don't think EVs will ever drop down to the price point of our 2009 Mazda (£500), that's because even a written off/unroad worth Leaf has a 24kWh lithium ion battery pack that can be reused for home energy storage. I suspect if you can nab a Leaf for sub £5K now you will not loss a single penny in deprecation for at least 3-5 years, may be even longer!!
If we couldn't financially justify/afford a Tesla I would have no problems owing a used Leaf to get me from A to B. Great little car, but still big enough to carry a bike without taking the wheels off. You could literally refuel it anywhere, even a farm on top of a hill somewhere in the peak district
