EVs won’t be massively different to regular ICE cars, I suspect.
Fewer things to go wrong, & components like brakes & pads last much longer with EVs, most of which would use a regen feature far more than pads for actually slowing cars.
We had a Kona for over 5 years & found it was valued around £11k after a list sale price of £36k. An expected depreciation compared with other cars.
Traded up to an ex-demo 3 month old one that’s was (surprise surprise) over 35% off original list price….
There are Tesla’s out there with over half a million miles on.
Batteries degrade, but the feeling is it is only around 1-2% per year, so if you have a 250-300 mile range to start, after 10 years you should still have over 200 🤷♂️
The main issue right now is that EVs are still at least 10-20% more than an equivalent ICE car from new…..but Chinese cars are coming in to sweep the market - companies like BYD, who have taken over a bunch of dealerships to establish a presence, and have lowered prices.
If (when) there is the next leap in battery tech, that could impact prices, but the broad 2nd hand market is fairly established.
A more interesting question (IMHO) is how Musks political views are impacting the Tesla brand. Several reports suggest he is putting a third of buyers off, which must be hurting sales. You couldn’t get a barge pole long enough to tempt me into one, but secondhand prices appear to be fairly sharp for them.
