The Mercedes-Benz GL-Class is a full-size luxury SUV produced by the German carmaker Mercedes-Benz since 2006. A three-row, 7-passenger vehicle, it slots above the Mercedes-Benz M-Class in the lineup and is the flagship of the Mercedes-Benz SUV line. The GL shares the same unibodyarchitecture with the M-Class. The vast majority of GL-Class vehicles are assembled at Mercedes-Benz US International, Inc, in Tuscaloosa County, Alabama except for a small number of early production 2007 model vehicles which were manufactured in Germany. The first generation (X164) was manufactured between 2006 and 2012 and was replaced in 2012 by the new generation GL-Class (X166).
