Yahoo! Autos has partnered with Kelley Blue Book to provide you with used car pricing estimates. To get an estimate on the price of a used car go to the used car tab of Yahoo! Autos and select "Blue Book Pricing." You can select either a buying or a selling path to price a car. At the end of the four-step process you will be able to view both a buyer's and a seller's report for that car. You will be asked for make, model, and year information in addition to style, options, mileage, and condition information. All of this information is used to determine the value of that used car.

Kelley Blue Book Pricing includes retail, trade-in, and private party values. Retail and trade-in values refer to the price you would expect to pay at a dealership or the price a dealer would give you on a trade-in. Private party values refer to the price you would expect to pay or receive if in a person-to-person transaction.
