Oh no, you're not getting me, I love depreciation. Re-read the first sentence.
Yes, it’s a good thing for buying a very used car.
Depreciation doesn't stop after 2 years. If you're the second owner of a lightly used car you intend to sell before the battery and powertrain warranty is over (as most do with EVs, at least here), you still get a fuckton of depreciation happening in the next few years with an EV, less so with ICE. If you're looking at something older, the extra depreciation benefits you a lot.
Personally I'm waiting for good 7-8 year old EVs to exist that are not Teslas. We're just a few years out from that for many popular models, at which point you can have the car of your dreams for 20k. For cars that were 100k new. If you get one that's 2 years old, it might still be 60-70k. Once that 100k car is around 20k, there's so little left to drop, you give no fucks. Even in my country there are now EV shops that will repair battery packs instead of replacing them so a few years of warranty isn't worth paying tens of thousands more for a car if you can probably get a battery pack repaired for <=5k in the very unlikely event that it fails. I'm not talking about gradual degradation, that's natural and not a big deal IMO with modern battery packs, I'm talking about actual sudden cell failure that leaves the car as a paperweight.
I've been looking at Jaguar I-Pace as I consider these sufficiently depreciated (can have one for ~15k), but I'm not a huge fan of crossovers and I dislike that most have no tow hitch and even if they do, they're rated to tow only 750 kg.
And to clarify while normally under "very used" I would mean 15 years or so, which is about what it takes an ICE vehicle to become properly cheap, for EVs this is slightly less, as you can get them super cheap at, like I said, ~7-8 years already.
I just meant that buying one that's 2-3 years old is still hella stupid because the next few years will continue to be brutal.
