Interesting, I just checked on the most popular used car listing site for my region to check if things changed since the last time I was interested - at least in my region, electric cars deprecate massively more here even now.
You get a price drop of 60-70% within 40-60k km for electric vehicles, the ICEs usually only drop by ~50% by 80-100k km. That's less deprecation despite higher usage.
And these electric cars are mostly ~4 years old while the ICEs are 6+ years old.
At least in my region, ICEs resell way, way better
/Edit: the Mazda 2 costs 21k€ new, the byd dolphin 30k.
If you're buying a 4years old Mazda for 1/2 of the price of a new byd dolphin, you're actually paying 70% of the list price of the Mazda.
That's kinda proving how high ICEs are reselling vs the electric vehicles. The equivalent electric vehicle would've deprecated more
