WESTLAKE VILLAGE, Calif. — On July 1, J.D. Power completed its acquisition of NADA Used Car Guide, a transaction that was announced in May.

The investment will combine Power Information Network (PIN) from J.D. Power, which provides analytics of new- and used-vehicle retail sales and pricing data, with the extensive knowledge, expertise and market presence of the NADA Used Car Guide, officials said.

"NADA Used Car Guide, with its vehicle valuation capabilities and analytical solutions, is a perfect complement to PIN's expertise in new- and used- vehicle retail and pricing services," said Finbarr O'Neill, president of J.D. Power. "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."

In a press release on June 30, the National Automobile Dealers Association’s Chairman Bill Fox said the decision to sell the Used Car Guide to J.D. Power was “not reached easily or without careful consideration,” but he believed the move will benefit the association’s members and advance its core mission to protect the interests of dealers.

“The Guide business will continue to grow and become an even stronger industry resource under J.D. Power,” Fox said. “As part of its agreement with NADA, J.D. Power will continue to provide NADA members with a complimentary Guide subscription as a membership benefit.”
