Overview
The 2008 Mercedes-Benz GL-Class is a full-size luxury SUV designed to deliver three-row family space with Mercedes comfort, technology, and all-weather capability. As part of the first-generation GL (X164, introduced for 2007), it targeted buyers who wanted an upscale alternative to large American SUVs and premium competitors like the BMW X5 (with more third-row practicality). It’s ideal for drivers who need real seating for up to seven, strong highway manners, and a premium cabin, and who are willing to keep up with higher-end maintenance. In the used market, the 2008 GL-Class is often chosen for its value-packed luxury and towing ability, balanced against known age-related repairs.
Key Features
- Three-row seating and big-cargo versatility: Standard 7-passenger layout on many trims, with a roomy second row and a usable third row for kids or shorter adults.
- Engine options: GL450 with a 4.7L V8 (smooth power and strong towing), and GL320 CDI with a 3.0L turbo-diesel V6 (excellent highway range and torque). Some markets also offered other variants, but these are the most commonly searched and shopped in the U.S.
- 4MATIC all-wheel drive: Standard AWD on most GL models, helping traction in rain/snow and providing confident long-distance touring manners.
- Optional AIRMATIC air suspension: Adjustable ride height and a cushy ride when healthy, plus self-leveling for passengers and cargo.
- Luxury and safety tech: Available navigation, premium audio, power liftgate, parking assistance, and a solid suite of stability/traction systems typical of Mercedes in this era.
