What are the Auction values?

The auction values that appear in the NADA Values Online program reflect current week auction activity. If the specific vehicle in which you are researching is not at auction this week there will probably not be an auction value reported for that vehicle.

If you need auction transaction data for a specific vehicle you are probably better served by a subscription to NADA AuctionNet Market Report. 

As background, regarding Auction Values in the NADA Values Online program:

Auction Values are derived from an industry-leading sample size of auction sales transaction data. Our analysts review the data to ensure accuracy and reliability, and update the  electronic offering information weekly.

There are three categories of auction values: Low, Average, High.

Auction values represent recent price action for a vehicle at wholesale auction and are available for the 11 most recent model years, as volume allows. They are defined as follows:

  • Low Auction Values represent vehicles with below average auction prices. Vehicles in this category may be negatively impacted by short-term oversupply and/or require substantial reconditioning.
  • Average Auction Values reflect the average auction price.
  • High Auction Values represent vehicles with higher than average auction market prices. Vehicles in this category may be positively impacted by short-term shortage in supply and/or in excellent condition with attributes or option content that would improve demand.

We do offer the full AuctionNet data set as a separate product, which includes all transactions from every U.S. Manheim, Adesa, ServNet, ABC and many independent auctions.  It contains approximately 80% of all auction activity nationwide and is delivered as raw data via FTP on a weekly basis.  If you’d like more information about the full AuctionNet data set, please visit
