NADAguides vs Edmunds

Proudly serving buyers and sellers of various vehicle types, both companies calculate and publish vehicle values based on proprietary methods.

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 its PIN data), as well as asking price information from 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.
