Cant say I pay much attention, just when i was searching for a cheap daily that had to be less than 5 year old for work, (and cheap) i googled fastest depreciating cars and the leaf was on every list (along with various Fiats and the pug 308/508) I got a 15 plate 308 for under 6k with 70k miles (20k list price new) A quick autotrader search shows you can get 15 plate leafs (with much much lower milage) for under 10k and i think they had a 25k list price new, still a big hit in the wallet for anyone im sure you will agree.
My concern is that EV cars will replicate the mobile phone recent era. So honda/ford/vw whoever launch a 100 mile range car then 2/3 years later update it with a 200 mile version with better tech and options for not much more (due to battery tech and scale of production) which sees the previous generation prices plummit and no one wants them. Then another 2 years down line and its now a 400 mile range and self driving meaning the previous gen 2 model suffers the same fate and so on until it gets to a point like now with iphones whereas the “new” model released is only marginally better than the last and there is not as much demand or people wont pay the extra so keeping used prices high.
It then finds a level cycle like we have had with combustion cars for so long until the next phase comes along, like flying cars, and the process starts again.
