I don't have any data on me to be honest, most of what I hear is based on people I know purchasing second hand EVs, and from what I know of EVs. They suffer from battery degradation which right now is an expensive swap, and charger compatibility is heavily dependent on infrastructure that takes forever to roll out where I am. Internal combustion engines will run great even after 150,000 kms, whereas conventional electric cars and even hybrids show degradation at 80,000 on a few models.
Newer EVs likely have less of these problems, but when I talk of purchasing second hand, I'm talking cars that are 10+ years old.
That's good to know, that means in the next 5 years, EVs will be as practical to purchase (used) as ICE cars are.
