The Infiniti M is a line of mid-size luxury (executive) cars from the Infiniti luxury division of Nissan. From 2013 on it has been marketed as the Infiniti Q70, reflecting the company's new naming scheme.

The Gloria is a large luxury car made from 1959 by the Prince Motor Company, and later by Nissan Motors since its merger with the former - hence being originally marketed as Prince Gloria and later as Nissan Gloria. Initially based on the smaller Prince Skyline, the Gloria line was merged with Nissan Cedric starting with 1971 models and both continued until 2004, when they were both replaced by Nissan Fuga.
