Another related topic: we should not change cars all 3 years. Why not drive them 20-30? Get replacement parts when needed, get the interior freshed up every 15 years and be happy. With the rising of electric cars, the only really critical part has become the batteries (and they seem to last longer than what we all thought).
The most I've ever paid for a vehicle is $19K for an almost fully loaded compact SUV with about 50K miles on it. The only reason I bought it is because the used $14K SUV I bought in 2014 was totaled in a car wreck. I was 4 payments left from fully paying the car off and had absolutely intended on continuing to drive it for another 8 years or so. Same with this one.
