I personally do not put a lot of faith in KBB for Tesla. Tesla pricing fluctuates so much and they don’t follow the typical model year updates like other companies. They make incremental updates all the time, so much so that even the same production years can have massive differences.
With that said, most people buying a Tesla are familiar with how Tesla operates, and IMO track the actual platform / feature changes more closely than the model year itself.
I’m sure this can be argued both ways, but Tesla used car pricing is just as unpredictable as their new car pricing.
