The Bureau of Labor Statistics says its used-cars-and-trucks index rose 0.7% from August to September 2026 after seasonal adjustment. That followed 0.4% increases in both July and August after the index fell 0.2% in June.
Before seasonal adjustment, the used-cars-and-trucks index was 1.5% below September 2025. New-vehicle prices rose 0.2% for the month after seasonal adjustment and 0.6% for the year before seasonal adjustment. BLS may revise seasonally adjusted data during its annual seasonal-factor update.
What it means for buyers
The September rise does not mean every used car costs more. The yearly decline also does not promise a discount on one car. Supply, miles, trim, condition, history, location, and financing all shape the final deal.
Compare the same year, model, trim, mileage range, and condition in your local market.
Ask for the out-the-door price so taxes, fees, and optional products are visible.
Compare the APR, term, amount financed, and total payments apart from the car price.
Arrange an independent pre-purchase inspection before committing.
What it means for sellers
Check the market again instead of relying on the national monthly change or a year-old price. Use recent local comparisons. Clear service records and honest condition notes can help buyers understand your price.
Use the index as context, not an appraisal
The CPI tracks average price changes for urban buyers. It does not publish an average used-car price or value one car. Compare several current listings and value guides, then account for the car's condition.
