Electric cars face a lot of depreciation, so you can get a really good deal on a used one. Plenty of supply, low cost, and cheap to keep running.

I'm not sure this will be the case going forward, as much of the depreciation in the past was due to Tesla's $10K+ price drops, the cancelled EV rebate, and luxury manufacturers making bad but expensive EVs.

That would work other way too, EVs would be expensive to upgrade to newer models. Though nowadays it is not that big a concern, but battery pack replacement at some point need to be accounted for.
