"read":"Wholesale prices firmed in October on tight supply (index +0.7% mix-adjusted, but unadjusted prices actually fell 2% from September). Retail listings are at a post-2022 high of $27,235 and inventory is building, which usually means dealers get softer on price by December. If you are selling or trading, do it now while wholesale is firm; if you are buying, inventory growth favors waiting a month and shopping aged units."}
