If you are not in the market for a new car, there are plenty of second hand EVs now. Including some that are close to 15 years old. Most of those will easily beat your ICE car on maintenance and fuel consumption. And they aren't that much more expensive even.
It's still 12,000UKP more expensive than the paid-off ICE 15-yo I have on my driveway, which is a heck of a lot of petrol.
