Exterior & Styling

Particularly from the rear, the GL's appearance looks a bit like Mercedes' original M-Class. The 21-inch wheels, oversized grille and chrome running boards on my test car gave it a look similar to that of Mercedes' AMG performance cars — perhaps that was the intention, given that there is no AMG GL-Class — and should secure the car a front-row spot at most valet stands.

Less-expensive GLs have 18- or 19-inch wheels. An optional offroad package on the GL450 raises the air suspension to yield 12 inches of ground clearance — some 2 inches higher than a Hummer H2's. The package also has a two-speed transfer case and locking center and rear differentials.
