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.

Costco Auto Program

The Costco Auto Program offers a complete auto marketplace specifically for members of the membership-only warehouse club. The participating dealerships handle all the transactions. Users can shop for both new and certified pre-owned vehicles. The site also offers opportunities to find deals on service and parts along with exclusive specials and incentives.

The program covers seasonal sports like snowmobiles or personal watercraft, RVs, off-, and on-road vehicles like motorcycles and ATVs. Users can browse the selection of mobility vehicles too. Buyers receive discounted service and a $500 Costco gift card with these purchases. They can also get 24/7 emergency service on their driver assistance equipment.

The website has a build-your-vehicle feature that allows users to select the specs and amenities they prefer. It provides both MSRP and the member-only cost. There is also a complete list of specs with all the dimensions of the chosen option. They can calculate the monthly payment with the savings of the APR or rebate. Visitors must enter their membership credentials to search for certified pre-owned vehicles.

Members can select from nationwide manufacturer incentives for cash credit, lease deals, and special financing. They can also get a 15 percent coupon off of service and parts for automobiles and power sports. Gold Star and Business Members receive an one-time, 50-percent off coupon up to $100 in savings. Executive members tet the same discount up to $200 in savings.

The parent company established the Costco Auto Program in 1989 as an added benefit to its members. They have formed partnerships with over 3,000 dealerships across the country, making it easy for individuals to find the specific vehicle they want. Potential buyers must use the website to get prearranged deals from participating sellers. They do not offer an app currently.

The authorized dealer handles the final pricing, trade-in value, or other add-ons. The site only sells certified pre-owned and not used vehicles. The preset discount and Kelley Blue Book value determine the cost. Members must also complete a satisfaction survey after their purchase to receive the additional benefits of the Costco Auto Program. Over 2.3 million members have taken advantage of this perk.
