Tschuti - I have been keeping data on Soul EV deterioration data for the last couple of years - this car is below the average for deterioration of cars that I am monitoring. I have marked it with a cross on this chart. It is also below the warranty line, distance wise.
But it is well above the rapid deterioration seen in extreme cases such as Phoenix Arizona.
Edit : your warranty line is 150,000km not the 160,000km shown which is for cars outside Europe.
It makes it less likely that you will get a new battery under warranty.
I disagree with Schwaendi - deterioration mostly slows with age. Only in extreme cases such as a single total cell failure, or when pushing a failing battery to perform above its capability does deterioration speed up.
Tschuti - to know whether this car is good value or not you would have to post the age of the car.
