EV's are full of technology. Resale and appeal is like buying a used computer or phone more than buying a used car. The tech is moving along quickly and most people that currently buy EV's want the leading edge of inovation rather than generations past.
As was pointed out in the article, purchase price is higher for a similar sized combustion driven vehicle and government incentives are being reduced that help with that differential.
I can see used EV's sales being the most popular where there are restrictions introduced where you can operate a combustion engine. It will force people to EV's and used may be their only affordable choice.
