Inside the 2007 Mercedes-Benz GL-Class, leather and burl walnut wood dominate, and there’s a standard power sunroof with a fixed glass panel located over the third-row seats. When the power split-folding third-row seats are not in use, the GL-Class can carry 43.8 cubic feet of cargo. Fold the second-row seats and it can manage up to 83 cubic feet of stuff. As with the M- and R-Class models, a long list of optional features including Premium, Sport, Comfort, and Entertainment packages is likely to be available, along with features such as a navigation system, satellite radio, and Keyless Go ignition.
