Here is the reply I received to the message Sent to NADA concerning the "Free" info compared to the "Purchased" info.
To Whom It May Concern:
Thank you for contacting NADAguides.
NADAguides offers a number of different products that are updated at varying frequencies. You’ll find that some of the automotive products found on nada.com are updated more frequently than others.
With respect to the RV products, more often than not, you will find that the Average Retail value will be the same across the print and electronic products (keeping in mind, that we have the ability to make real-time updates to the electronic products that we might otherwise not have the ability to update in print).
Additionally, the free consumer website will offer Low and Average Retail prices to assist the consumer with their RV buying or selling decisions. The subscription trade products (whether print or electronic) will offer the dealer a Used Wholesale/Trade-In and Average Retail price.
You also mention the sample size of data. Our Analysts are constantly analyzing used sales, auction results, and other pertinent market data. We also have a large Advisory Board of dealers that are surveyed three times each year (additional surveys may be sent if necessary).
Should you have additional questions, please feel free to contact me.
