NADAguides vs BlackBook Values

NADAguides (National Appraisal Guides) and Black Book Values offer vehicle valuation services based on a proprietary collection of data points and professional market analysis. Black Book Values service offering differs from NADAguides in the fact that they do not offer direct to consumer services. Rather, their services are ready made for businesses such as auto lenders and dealers.

National Appraisal Guides (NADAguides)

When we attempt to value a used vehicle we use a number of data points. These data points include, but are not limited to, actual wholesale transactions (around 80% of the market with our relationship with NAAA) and retail transactions (through our relationship with J.D. Power and their PIN data which is obtained their actual Dealer Management Systems), as well as asking price information from www.autotrader.com. In addition, we have data from various OEMs and wholesalers and retailers of used vehicles that provide us the amounts for which they paid and sold their vehicles. We also take into consideration MSRP, invoice, equipment assumptions, as well as supply and demand and other macro- and micro-economic factors and the competitive landscape of vehicles. Our retail value is what a person could reasonably pay for a vehicle at a dealer’s lot. Our values are designed and intended to assist users in performing their own valuation of a particular used vehicle. The process by which users of NADAguides determine valuation is inherently subjective. Individual vehicles may have an actual value that is higher or lower than the estimated values created by us.


NADA has been around for over 80 years and is the premier valuation guide in the used vehicle industry. Customers include, but are not limited to: dealers, wholesalers, rental car companies, insurance companies, lending institutions, OEMs, government agencies, as well as individual consumers. We attempt to create the most accurate, market-reflective, unbiased vehicle values and we believe we do so each and every time one of our products is presented to the outside world.


NADAguides is additionally known as a credible source for pricing outside of the automobile industry. Comprehensive pricing data is also published for powersports, recreational vehicles, boats and manufactured housing.

Black Book Values

Black Book Values focuses on data points that can help lenders and dealers better identify vehicles with lower risks and higher potential profitability. Their pricing and value data includes statistical analysis that allows for current and time-sensitive changes in historical valuation to be easily understood resulting in reliable predictors of values and potential risks.

The driving force behind Black Book’s valuation process is an understanding of what drives the auto market as a whole as well as what factors help set vehicle specific values. This includes essential data points like how key attributes such as mileage, maintenance records, model, year, and trim options affect value. Beyond those core attributes, Black Book Values are affected by industry trends, depreciation rates and curves, future predictions, and much more.

These future predictions differentiate Black Book Values in the fact that they are not only providing current pricing information, but are offering a look at how specific vehicles will be valued in the future. When making residual value predictions, the company will weigh factors such as year-to-year model and design changes, historical understanding of a make or model’s market performance, economic factors, and much more. This data analysis allows dealers and lenders to manage and better calculate their lending and inventory risks.

By providing current car values as well as forecasting predictions, Black Book Values is uniquely positioned as an one-stop-shop for businesses that need to accurately manage and weigh risks associated with their physical inventories and lending obligations.
