I am saying they are still very cheap to run as long as you can charge on EV tariff, nothing has changed from 2017 when I got Leaf to now.
On more upfront costs, looking at used EV prices, I don't think owning an EV will be a costly experience thanks to high residual values and ever higher demand for used EV's. Same as Leaf, I'm pretty confident my Model Y will effectively be riding the wave front of limited used supply curve for a highly reputable car. Just look at prices for cheapest used Model 3.
Here's a good example, my Nissan Leaf was just under £9000 from main dealer back in 2017. Now asking price is higher for a slightly older car at an indie dealer: https://www.speakev.com/threads/for...-acenta-24kwh-3-3kw-charger-57k-miles.172501/
Another case in point: I sold my Skoda Octavia diesel for £5200 to a dealer, advertised privately and all the questions were "is it ULEZ compliant?" zero interest after that. I am confident I can sell my Nissan Leaf for well over £8k to a dealer. In fact, motorway are offering £8,739 for the Leaf while £5000 for Octy. Both were bought in 2017 for similar price. Granted, current used market is crazy, but I wouldn't expect such a huge difference between cars that used to worth so similar.
So I can only put it down to changing public perception that created ever increasing demand. When demand for cheap used EV out strip a very limited supply......
