While 15 million used cars are sold every year, the average person has little idea of what price to ask for a vehicle and what to pay for one. Everyone has heard of the blue book value of a car, but until 1993, the Kelley Blue Book Used Car Guide was only available to auto dealers, financial institutions, and other businesses. The Consumer Edition arms buyers with the same knowledge as sellers. The recognized authority in used vehicle pricing, the Consumer Edition is published twice a year, with vehicle identification numbers, original list prices, and two retail values (for good and excellent condition). Covering 10,000 models of cars, trucks, and vans, it also includes easy-to-use equipment schedules with values for optional equipment and a table of acceptable mileage ranges by year.
