That makes sense and is a perfect analogy. I was talking about the used car market with friends a few days ago, and we discussed exactly that: the used car market is gentrifying because the insane price of new cars today is slowly but surely reducing the supply of good-condition used cars! I don't have data to back that up, but that was the lunchtime theory, and if you've tried to buy a good condition used truck recently I think there's at least some basis in fact.
