"Only" 1 out of 3 e-golfs in finn are from 2016. I think it happens more often in the elbil market. Maybe one doesnt buy it with the idea of selling it one year later but suddendly the car is outdated.

I am just discussing and open to hear the ideas. I am like dibun, I would need a car and I want to buy an electric car, but many new things are expected within 18 months.....what to do in the meantime?

Price is around 250k , he will pay 50k , so 20% of the value, which is quite close to what you are suppose to lose after one year for a new car.
With the current market, if you buy instead, are you sure you can sell it for more than 200k after this first year?....well I am not sure. Leasing is an option where you fix your loss. It could be that the drop with the new Leaf plus the new comers is even bigger.
Ok , a good deal would be to pay 15% so 37.5k ....but nobody would give you that, but the question is ...is it leasing too expensive or the elbil market currently bad for second hand cars?

This one?
