Not all EV's are created equal. Tesla though have introduced pretty good guarantees on their batteries and drive trains at 8 years and between 190,000km and 240,000km at minimum 70% battery retention depending on model. Now you can probably fork out for a new one, refurbished one or have cells swapped out in the same way you can have an engine or gearbox overhauled. The difference is at the current pace of battery development we should see this increase to the useful life of a vehicle or the tesla-touted "million mile battery".According to the starry eyed optimists here they will far outlast ICE vehicles. So it should be about two decades before we start seeing the first EV skedonks. But the most expensive part is the battery and when that dies the skedonk dies. You can't fix it with wire and tin cans like you can an ICE skedonk.
Also, any EV is a theft target just for it's electrical component non ferrous material scrap value. If they're chopping steel rebar out of concrete structures for scrap, your EV will be worth a lot more.
And as for theft targets that's just nonsense. There's more scrap value in a regular car than an EV.
