Another issue is that if the batteries are stored with either too much or too little charge... they deteriorate quickly and the damage cannot be reversed. The most expensive component in an electric car is the battery. Once it is shot... in many cases the vehicle can be left with almost no value at all.
In the secondhand market for gasoline-powered vehicles, there’s a certain amount of rationality based on decades of experience driving such vehicles. For a gas-powered car that has say fewer than 30k miles, buyers might pay 70% of the new vehicle price. For a gas-powered car that has say more than 100k miles, buyers might pay 20% of the new vehicle price. This is all based on the buyers’ expectations of remaining useful life of the vehicle, maintenance/repair costs, etc. The EV industry is still so new that, to most buyers, estimated remaining useful life of an EV, maintenance/repair costs, etc. seem like a total wildcard. Can you get a 100k miles on an EV battery? If you can’t, how much will it cost to replace the battery? Not a ton of people thinking about these questions
With a used gas car you can repair an engine but not an electric battery powered one. You would wonder if that electric car will explode in flames just sitting there in your garage or while driving. Bad enough worry when brand new!
We simply live is stupid times.
