Of course the car in your example has lost a huge amount per mile - it’s a two year old car with ridiculously low mileage - not a great use of the manufacturer’s warranty either there.
As a chalk and cheese comparison I bought a used 6.2 petrol car that had lost a similar amount ‘per mile’ in depreciation terms (and that was after seven years/11k miles IIRC)
Not really the norm?
I think it’s fair to say that resale on EVs isn’t/wasn’t the attraction of them - who ‘buys’ a new EV anyway? Aren’t they pretty much all discounted to leasing companies and rented monthly like many people do with their mobile phones?
In other words, who goes looking to purchase outright an expensive second hand EV when you can rent/lease a brand new one so easily (and get the newest model with all the incentives on offer etc)
I don’t think that resale values on an expensive premium EV such as this shows anything much in terms of people not wanting one but just indicate that it’s often more attractive to source/finance a brand new one (with the various incentives that may be available) for those thst can afford expensive cars such as these.
Perhaps once a larger number of these (quite expensive) vehicles drop to a level whereby your average older used car buyer can afford one (£10/20k?) then the rest of the market will settle down a bit too?
