That's somewhat helpful, especially the last two quoted sentences.

But for the other part they track luxury at the model level. If you get a jeep or truck that cost $50k-80k because you wanted heated/vented seats, a panoramic sunroof, etc then it's not included in luxury.

I think part of this is also inflation (seems like some sensational journalism dor modt of the articles I found - using average instead of mean and not using inflation). Inflation from December 2017 to December 2022 would mean a $20k car in 2017 would cost $24k in 2022 adjusted for inflation. That's a huge jump.
