the second biggest cost (after purchase) is frequently ignored - depreciation
History no predictor of future price, of course, but I'm happy ...
First 2015 MSP I had was circa £100K - for a former a VW Golf BlueMotion buyer - shafted by DieselGate - that was a big step up.
£100K cars are not renowned for strong residuals! at 3.5 years and 95K miles I traded it in for another and got a 50% trade in.
The M3 I swapped for an MY in February had a strong trade in too - the market was crazy for used cars then of course ... but my perception was that my EV trade-in was better-still than an ICE trade-in.
My crystal ball gazing suggests:
In, say, 3 years time when a new-today EV is sold it will be much in demand. Price of ownership of ICE will be tanking (either increased tax on Carbon Fuels, or everyone saying "ICE is a dead-end" or "How come my neighbour got an EV first"
)
Between now and then the number of new EV sales will increase dramatically.
So I think at sale time it will be the perfect-storm of more-buyers-than-sellers. Today's number of sales of new EVs will be tiny, compared to then, so current owner will be one of very few to have that model / age / mileage that 2nd hand buyer wants
It is possible that Tech will Leapfrog and cause plunging new car price - e.g. a breakthrough in battery tech (unlikely, but) - but that would mean that the replacement new is much lower, so 2nd hand resale will be lower too, but "make-up differential" will be equivalent
See you in 3 years to see how the predictions went
