According to the National Automobile Dealers Association, over 60 percent of the vehicles on the road are 12 years old or older. The Consumer Edition of the Kelley Blue Book Used Car Guide gives buyers the hard information they need to avoid being ripped off when they buy one of these vehicles. The only recognized authority in this field, this guide offers information once offered only to the automotive industry. It covers current private-party values, trade-in values, and retail values of over 10,000 models of used cars, trucks, and vans for the past 15 years. Published twice a year, with updated values, the Consumer Edition includes VIN numbers, original list price, easy-to-use equipment schedules with values for optional equipment, a table of acceptable mileage ranges by year, and tips on buying a used car.
