How these numbers are made

  • Every figure is a final bid: what a lot sold for at Copart or IAAI in the United States, without auction and delivery fees.
  • Sales are counted once a month for every make, model, generation, model year and engine. A month on this page is the month the cars sold.
  • "12 months" means the last twelve months shown; a change compares them with the twelve months before, and is shown only when both have enough lots.
  • Placeholder bids that some feeds send (such as $999,999) are taken out before averaging. Encar is left out: its prices are dealer asks, not bids.
  • Averages describe the market, not a single car: damage, title and mileage move the price of one lot far more than its year.
