The N.A.D.A. Official Used Car Guide Co. (N.A.D.A.), specializing in used-vehicle values, and Automotive Lease Guide (ALG), specializing in residual vehicle values, on Oct. 20 announced a collaboration that brings together two leaders in the automotive valuation industry. The N.A.D.A./ALG Web Referral Program grows out of this strategic partnership and encompasses two products: ALG's Fleet Residual Model and their Online Calculator. "This is an unprecedented joining of forces that rounds out the offerings found on, making it a one-stop source for vehicle valuations," the companies said in a prepared statement. When N.A.D.A. online customers purchase an annual agreement for either ALG product promoted through the link, one free month will be added to the end of their contract. After logging on to their accounts at, customers will be able to use the promotional button to link to a specific co-branded page on ALG's site. During a one-month promotional period (Oct. 20 - Nov. 21), ALG exclusively provides N.A.D.A.'s B2B online customers free access to either their Fleet Residual Model or Online Calculator. N.A.D.A., specializing in the new and used car and truck market for more than 70 years, will promote residual products to its customers, especially those from the leader in the residual valuation industry. "We are excited to join forces with ALG," said Scott Lilja, executive director of the N.A.D.A. Official Used Car Guide Co. "Our mission through this partnership is to create additional opportunities for our customers to access the highest quality vehicle data from the leaders in both the used and residual valuation business."
