We have bought an electric car!

I fail to see the point here.
All vehicles depreciate to some extent. I have purchased new ICE vehicles in the past which have massively depreciated and the scarce few which have done so only marginally.
Purchase a luxury European vehicle and the depreciation will make your eyes water!
I would suggest any vehicle owner of any motive power, seeking your “free lunch” would probably be left bitterly disappointed in that regard.
Driving an EV, is not purely about fuel savings either, although that is welcome now fuel is above $3 per litre, it is also about one’s personal choices.

A decent new EV is twice the price of a new petrol vehicle so inherently more to lose on depreciation.

Another inaccurate generalisation.
A new Audi, BMW, Mercedes, Jaguar, Range Rover, Porsche, etc, etc, etc, twice the price (and more) of our mid price range (decent) ev so inherently more to lose.
People can spend as much or as little as they personally wish on a vehicle, so this depreciation nonsense is irrelevant and frankly exactly the epitome of the “hate” I spoke about in my original post folks.
