It could, of course, be a question of availability, but would you buy a used EV over five years old?
Then your looking at Tesla, Gwizz or a Leaf... And it's a 'No' for all three, albeit for different reasons...
Tesla, see my last post, and there's plenty more interesting things for the money.
Gwizz. I wouldn't buy one for my worst enemy, even if it was their birthday.
Leaf. Only as a local car, which means something else for most of the time, and if you need to run a second car to negate the short comings, then why bother? On this point, if Albs can charge it at work, then that's at least halved his 'fuel' costs.
But ultimately noone is going to warranty £10-30k of battery on a 5+ year old EV, which makes them disposable.
A hybrid of any flavour is always going to be a better used buy because it doesn't rely on the battery for power.
