WESTLAKE VILLAGE, Calif. — J.D. Power and the National Automobile Dealers Association (NADA) have announced an agreement under which J.D. Power will acquire NADA’s Used Car Guide business, a well-known source of used-vehicle values. The transaction is expected to close early in the third quarter of 2015 and is subject to Hart–Scott–Rodino Act review.

Established by NADA in 1933, NADA Used Car Guide is a provider of U.S. retail, loan, trade-in and auction used-vehicle values, and is widely recognized in the industry as the authority for accurate and comprehensive used-vehicle valuation information. The company will remain based in the McLean, Va., vicinity where it serves more than 100,000 subscribing clients, including retailers, financial institutions, insurers and software providers.

“This deal is a perfect fit for dealers and NADA Used Car Guide customers. Under terms of the deal, NADA members will continue to receive a subscription to the Guide as a membership benefit,” said Peter Welch, president of NADA. “NADA and J.D. Power will continue to build upon our longstanding alliance by sharing data and insights, and bringing together retailers and leaders from the automakers, suppliers and the media at co-hosted conferences and events, offering thought leadership and solutions directly benefiting the retailer network and overall automotive industry.”

J.D. Power is a global marketing information services company known for using the voice of the customer to create reviews and ratings which measure the shopping, purchase and ownership experience across a wide range of brands and products. The Power Information Network (PIN) from J.D. Power provides real-time automotive information and decision-support tools based on the collection of daily new- and used-vehicle retail transactions.

“We are thrilled to add the NADA Used Car Guide and its vehicle valuation capabilities to J.D. Power,” said Finbarr O’Neill, president of J.D. Power. “NADA Used Car Guide analytical solutions will perfectly complement PIN’s expertise in new- and used- vehicle retail and pricing services, and we will gain an impressive array of integrated vehicle valuation solutions. The Guide’s high integrity and unbiased approach to used-vehicle values, analytics and insights fits perfectly with J.D. Power’s reputation as a trusted advisor to the automotive industry.”

The agreement brings together PIN, which combines advanced analytics of new- and used-vehicle retail sales and pricing data, with the complementary and extensive knowledge, expertise and market presence of the NADA Used Car Guide, thereby expanding J.D. Power’s analytical and modeling capabilities into new product offerings, deepening its presence in auto finance and auto insurance, and enriching retail solutions, officials said.

The NADA Used Car Guide name will be used by J.D. Power for a period of time before transitioning to the J.D. Power brand.
