Considering the Model X is an electric car, and has significantly fewer moving parts than an internal combustion engine vehicle; is an odometer reading really an appropriate representation of residual value? Would 20 000 miles in a Tesla really represent the same wear and tear it would for an ICE vehicle? Aside from tire tread and brake thickness, which are standard measures what would the ratio be? I would be hard pressed to find a correlation between ICE mileage and BEV mileage. Would one mile in an ICE equal three in an EV? Resale value needs to re-reassessed in this case. Just another reason in my opinion to buy EV.
