“The Mercedes-Benz GL-Class is large and capable off road yet feels surprisingly car-like on the road. That car-like feeling comes in part because this is the first full-size SUV built around a unibody architecture instead of traditional body-on-frame construction.” — New Car Test Drive
“The GL-Class has strong acceleration from the gasoline V8, gas mileage in the 20s with the diesel V6, quiet interior, many available luxury amenities, excellent fit and finish, and comfortable seating.” — Edmunds.com
“Ride quality might be a little floaty for some.” — Edmunds.com
“The GL is a worthy entry in its segment, but it has none of the charisma of the Cadillac Escalade or Mercedes-Benz's own G-class, which it was supposed to supplant.” — Automobile
