NADAguides - KBB vs NADAguide Values - Kelley Blue Book (1)
Thanks to the internet, information that was once hard to find is now easy to reach in seconds for anyone. Many websites will show you any information you could ever want to know about a car. For the car you own, you can find the value of the car if you trade it in or decide to sell it yourself to another person.

Many sites are competing for your attention. Most sites claim that they have the most accurate information. But how can you tell one site from another? Is there really a difference between NADAguides and KBB?

NADAguides Used Car Values and Kelley Blue Book (KBB) have a long history of providing values to consumers and businesses alike. Both sites calculate values using their own specific methods, which aren’t always widely known.

Of course, if you are already ready to get the value of your car or research a new or used car, there’s no better destination than

What is NADAguides Value?

NADA stands for National Automobile Dealers Association, a name that reflects the company’s long-time status as a source that car dealers rely upon when making a deal. Today, they call themselves NADAguides, (without the “used car”) now that they are making their values available to the public and have added new car pricing to their used car values.

With a long history of valuation expertise, the NADA Guide has been around since 1933. Similar to Kelley Blue Book, the NADA Guide also provides values for cars, trucks, SUVs, and vans and works with professionals in the automotive, financial, government, fleet, and insurance sectors. For individual consumers, NADAguides is generally less well-known than Kelley Blue Book.

NADA also uses many data points from a variety of sources to give a value for a used car. They include wholesale transactions like auctions, retail transactions (actual vehicle sales at dealerships), and pricing information from sites like Autotrader. In addition, NADA uses data from the vehicle manufacturers themselves and from the companies buying and selling used cars to come up with their values.

When calculating a vehicle value, NADA uses many of the same considerations as Kelley Blue Book: MSRP and invoice (for new cars), mileage and general condition (for used cars), and assumptions about the equipment on the vehicle for all values. NADA may adjust the value of a vehicle based on macroeconomic and microeconomic forces, like supply & demand and the state of the market at any given time. It is unknown to what extent NADAguides provides specific values tailored for different parts of the country, as Kelley Blue Book does.

Based largely on condition, a used vehicle you own could be categorized as “Rough Trade-In”. “Average Trade-In”, or “Clean Trade-In”. For used vehicles you might be interested in buying, NADAguides has only one classification: “Clean Retail”. NADA Guides doesn’t show values for the private sale of a used vehicle, but it does show what it might cost to buy a Certified Pre-Owned (CPO) version of certain used vehicles.

Long an important source for car dealers, banks, and other members of the automobile industry, NADA Guides now makes their values available to the public at their site

NADAguides also offers values for motorcycles, powersports, boats, recreational vehicles (RVs, aka “campers”), and manufactured housing (often called “trailers”)

In 2017, J.D. Power bought NADA Guides and is now responsible for the data that drives its values.

Used Car Values and Prices:

  • Trade-In Value: The amount you can expect to receive when trading a car in at a dealership.
  • Private Party Value: The amount you can expect to receive when selling your car to another consumer. This value is typically higher than the trade-in value because, unlike dealerships, you don’t have costs like rent or salespeople to worry about.
  • Used Car Fair Purchase Price (retail value): This is the amount that a consumer would reasonably expect to pay to buy this used car at a dealership.
  • Certified Pre-Owned Price (CPO): For some newer used cars, the dealership may offer a factory-backed certification process. The price is usually about 10% higher than a conventional used car, but many people like the confidence of buying a certified car.

New Car Prices:

  • New Car Fair Purchase Price (once called the New Car Blue Book Value): This is the amount that a consumer would reasonably expect to pay to buy this new car at a dealership.
  • Where to see these prices: These values are displayed, both on and on dealers’ websites nationwide. Look for the Kelley Blue Book® Price Advisor. It has white, green, and red zones. If you see the price in the Green Zone of the Price Advisor, you can be confident that it is a fair price for both buyer and seller alike.

In addition to vehicles of all types, Kelley Blue Book also reports values for motorcycles.
