Adding to the remark in the article about new and used cars being linked at the dealers: many new car dealers do not shop at auctions. They only buy used trade-ins partly to help encourage new car purchases ie the "four square" calculation they use. So when their new car supply is interrupted upstream, that also interrupts their flow of used cars, so some dealer lots are a little thin on both new and used inventory at the moment.
