The Kelley Blue Book (also known as the Blue Book) is a must-have resource for anyone looking to buy or sell a car in North America. Established in 1926 as a regular print publication, the Blue Book provides comprehensive automotive pricing data to car buyers and sellers. The Blue Book collects and analyses information on new and used cars, trucks, and SUVs across North America, allowing buyers and sellers to make informed decisions.

The Blue Book collects details on the various models of used vehicles available, including their make and model, year, and comparable mileage. Their in-depth analysis allows them to calculate the Private Party Value, Trade-In Value, Suggested Retail Value and Certified Pre-Owned (CPO) Value of each vehicle, allowing users to accurately judge the worth of a car before they finalize the purchase. This makes the Blue Book an invaluable resource for car buyers, as it takes the guesswork out of pricing and helps them to make the best purchase decision for their budget.

The Blue Book goes beyond providing price estimates, however. It is also a great tool for prospective car owners to use to get a better understanding of the cost of car ownership. It provides data on the potential future costs of vehicle ownership, such as fuel, maintenance, repairs, and insurance, helping would-be buyers to get a better gauge of their overall spending.

Since its inception, the Blue Book has become a trusted and well-known resource used by car buyers and sellers in North America, and it continues to be an extremely valuable tool in the automotive marketplace today. It not only helps car buyers and sellers accurately assess the worth of a car, but it also allows them to get an accurate understanding of the total costs of ownership.
