Theres a variety of factors here. For one, more and more people are rolling their already stupid high loans into their next loan on a new used vehicle. So that is driving up the overall price. Second is that the new car market average price is well over $40k on average. Since people who cant get a new car have to buy used, then used car prices will creep as close to that point as they can regardless of actual vehicle values. The actual value of the vehicle is irrelevant in a country where cars are a necessity for the majority of people. What dealers are selling is the opportunity to have a vehicle more than the vehicle itself, and so they are gouging the shit out of people who have no reasonable alternative outside of buying on the used car market
