Would you never buy a used ICE car because replacing the engine would effectively total the vehicle? Batteries last a LONG time assuming the vehicle manufacturer has put proper heat and SoC management into the battery controller (ie, not a Nissan Leaf). I thought my 7 year old Ford Focus EV would be half the range of its 110mi battery by now but it still posts near-perfect range (it's lost about 5%).
