What's with all the people saying to buy used?

The current used car market sounds feels like a damn scam for most Americans in most of America. There's 120k 2005 Camrys going for $3000 almost ten years ago selling for $4000 now. "Always used!" "Used hands down!" "Go to carmax!" when post-pandemic, driving the car off the lot actually adds about 20% to the sale value than what you would end up paying for a new one. It just feels more economically sound to get a newer car.
