This 3-row, seven-seat GL-Class has two front-row seats, a middle-row bench that seats three, and a somewhat cramped third row that seats two. The first two rows of seats are comfortable, but the third row is best left to children. The second row folds to make accessing the third row relatively easy. The interior is well-insulated against outside noise. The GL-Class has complete LATCH child-seat connections in the second- and third-row rear outboard seats, plus a second-row middle-seat tether anchor.
Standard features in the GL-Class include dual-zone automatic climate control, power-folding third-row seats, satellite radio, a 115-volt power outlet, Bluetooth, and the COMAND infotainment system with a 7-inch screen. Available features include a navigation system, an iPod interface, a power-folding second-row seat, a rear-seat entertainment system, and an upgraded audio system. The COMAND system has clunky navigation controls and lacks a touch screen.
