Medians and ranges are USD completed sales; counts include every tracked currency. The 12-month change compares the past 12 months’ median with the prior 12 months’ and appears only when each window holds at least three sales — it tracks the median of what actually sold, so it moves with the mix of years, trims and mileages that came to market as well as with the market itself.
