NADAguides vs True Car Values

NADAguides (National Appraisal Guides) and TrueCar Values offer consumers accurate pricing information through detailed analysis and data aggregation on the national and local levels. Each of these companies are devoted to providing vehicle values on both new and used models for a wide variety of manufacturers.

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.

TrueCar Values

While TrueCar Values use broad data aggregation, analysing information like model year, miles, options, trim package, ect., their main focus is on providing reliable and accurate pricing information based on the actual sales price of similar vehicles.

By partnering with thousands of dealers across the United States, TrueCar receives reliable transaction data regarding how much a car sold for, the transaction date, as well as make and model information. TrueCar also utilizes third party data companies to gather further information to gain a more complete picture of each local auto marketplace. This data comes from a variety of sources and encompasses financing and loan data, vehicle registration and insurance data, and more.

Dealer and manufacturer incentives, rebates and discount programs are also researched and confirmed to help ensure that TrueCar Values and pricing information accurately reflect what consumers are actually paying for a vehicle.

To further ensure that pricing information is accurate, TrueCar updates pricing information weekly and checks for incentives and rebate programs daily. Transaction data is normally removed after it is 4-8 weeks old to make sure the provided pricing information accurately reflects current market conditions and what consumers can expect to pay if they were to purchase a car today. Updated information is usually published and available to consumers within 72 hours of TrueCar receiving and validating its accuracy.

TrueCar’s focus is on providing a more upfront and honest car buying and selling experience by making actual transaction information publicly available to both consumers and dealers in a clear and transparent way.
