Lmao!This has nothing to do with Tesla vs. other EVs, it has to do with the uncertainty consumers have for the unknown state of an EV battery in general vs. an ICE vehicle, whether it is valid or not. It is the same uncertainty consumers have for a used complex German ICE vehicle, just on a different scale. Both are known to be very expensive to repair.
Have you EVER seen leakdown percentages listed for used car engines ar any dealership that wasn't a true race shop?
I have only seen transmission clutch wear listed on sales data for older Lamborghini DCTs.
NO liquid cooled battery is losing more than 10% per 100k miles, and a general state of health by scanning voltage of individual cells is a quick, easy thing, esp compared to leakdown tests.
