NADAguides (National Appraisal Guides) and Kelley Blue Book both have a long history devoted to providing consumers as well as businesses with accurate vehicle pricing information. Proudly serving buyers and sellers of various vehicle types, both companies calculate and publish vehicle values based on proprietary methods.
National Appraisal Guides (NADAguides)
Longstanding relationships with manufacturers, dealers, auctions, financial institutions and other industry contacts allows NADAguides to calculate accurate used car values. With NADAguides, the data of more than 1.5 million vehicle transactions is processed on a monthly basis to ensure published values are accurate. Retail sales data, classified sales asking prices and auction transactions are some determining factors relied upon on for valuing all vehicles listed on NADAguides.com. NADAguides has earned its reputation by accurately utilizing statistics, analytics, and a deep understanding of the automotive market to calculate an accurate value. NADAguides publishes a Clean, Average, Rough and Certified Pre-Owned value for automobiles listed on its site.
Data for NADAguides is computed at a national and regional level taking into account the effects of macro-economic and micro-economic factors. On the NADAguides website, the values are published as a single national figure. For dealers, lenders, insurance companies and tax authorities, more targeted regional vehicle value information is available. Depending on the area of the country, there could be a differential of a few hundred dollars between the national and regional prices. NADAguides currently offers values on automobiles ranging from 1926 to the present year.
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.
Kelley Blue Book
Similar to NADAguides, values published by Kelley Blue Book rely on a constant flow of pricing information from various industry sources. Manufacturers, wholesale auctions, franchised and independent dealers, rental companies and financial institutions are sources for the data used to calculate vehicle prices.
The final used vehicle values are determined by Kelley Blue Book through a proprietary editorial process. Various values are presented on several scales, creating a unique price for every situation. The Private Party Value refers to the amount expected for a private sale of a vehicle as an individual. Trade-In Value and Suggested Retail Value prices are available for both sellers and buyers planning to interact with a dealer. Kelley Blue Book also calculates and provides values for the suggested price of an automobile at automaker-affiliated Certified Pre-Owned dealerships.
Finally, a Fair Purchase Price tool provides a snapshot of a vehicle’s actual selling price from tens of thousands of sale transactions. Differing from the other car value tools used by Kelley Blue Book, the Fair Purchase Price is sourced directly from vehicle sales through market contacts. Kelley Blue Book’s Fair Purchase Price tool is compiled from transactions conducted across the United States.
The primary focus of Kelley Blue Book is on automobiles but the company does offer values for a selection of motorcycles, personal watercraft and snowmobiles.
