How these numbers are calculated

What do the prices represent?

These are advertised asking prices for used and certified pre-owned vehicles, before taxes and registration. We use the lowest qualifying asking price per vehicle within 50 straight-line miles of the city center. The middle half is the range from the 25th to the 75th percentile. The median is a benchmark for this search; trim, mileage and condition affect what an individual car is worth.

What qualifies as a deal?

The price has to be 5–30% below our estimate, based on at least eight comparables for the same trim and model year. The estimate accounts for mileage where available, reported history and state. We leave out known modified cars from the deal ranking and exclude reported title issues from this search. Missing history doesn’t mean a car is clean. Confirm availability, vehicle history and the out-the-door price before visiting.
