How this number is made
Real sales and real asking prices from many sources, auction results and dealer and private listings, matched to this car by year, trim and body. Sales are one side of the market, what buyers paid; asks are the other, what sellers want now. When both sides stand on enough evidence the number is the mid between them, the way a market quotes itself. When one side is thin the other leads, and it says so. Sales from the car's own model year count first, older years only when its own year is thin, never another generation. Too few sales means no number. The line is what the number was each week, from every sale on file, and it ends at today's.
Known tests its own numbers. It hides each recent sale and listing in turn, prices that car from the rest of the market as it stood, and compares the result with the real price. The line under the number above is what that test found for numbers like this one.
