Reissued January Edition

In response to inquiries from customers and industry members about the NAGS benchmark and the recent overall market pricing changes published in the September 2016 and January 2017 NAGS benchmark, Mitchell has decided to undergo a review of the process and methodology for the NAGS benchmark.

As part of this process, Mitchell is reissuing the January 2017 NAGS benchmark. The January NAGS benchmark now consists of the September 2016 parts and pricing, and also includes new model year vehicle parts without pricing. NAGS customers will receive instructions on how to apply the January reissue.

Mitchell recognizes the importance of NAGS benchmark to the automobile glass industry and we believe this review is appropriate. We expect to publish the May 2017 NAGS Index as planned. Please contact John Gilmartin, SVP of Services & Operations, at with any questions.
