It's also worth factoring in the opportunity cost involved in buying an EV vs an efficient ICE equivalent and something modest vs. many flashy EVs.
$20K to $30K saved could be put towards locally-made, high-quality solar PV panels for your home, and other investments in the meantime.
With economies of scale, competition, technological advancements and mass adoption in the coming years, EVs will continue to become cheaper, so waiting and extending the life of your current vehicle could be advantageous.
Of course, I can't speak for everyone, but this is still some food for thought.
