Method terms: "same cars" is the median asking price of the same listings on both dates (a same-store median), so changes in the mix of cars do not move it; a "model" is a model year, make and model with at least 30 listings from 5 dealers (a cohort); a "group of states" is a U.S. Census division.

A market figure is published only with at least 30 listings from at least 5 dealers (no dealer above 40%). "Removed from sale" means a listing left the dealer's website; it is not a confirmed sale.
