What to Expect

Owning a 2017 Mercedes-Benz GLS is typically characterized by a sophisticated and premium ownership experience. Expect a vehicle that excels in comfort and quietness, making long journeys enjoyable. The advanced technology within the cabin is generally intuitive to use, and the vehicle’s performance, especially from the V8 models, is impressive.

• Maintenance: As with any luxury vehicle, maintenance costs for the GLS are generally higher than for non-luxury brands. Regular oil changes, fluid checks, and filter replacements are crucial. Expect to service your GLS at a Mercedes-Benz dealership or a qualified independent mechanic specializing in German luxury cars. Scheduled maintenance intervals are typically every 10,000 miles or annually. Parts and labor can be more expensive, so budgeting for these is advisable. Common maintenance items might include brake pad replacements, tire rotations, and potential replacement of air suspension components over time, especially as the vehicle ages.

• Insurance: Insurance premiums for the 2017 GLS will likely be higher than for more mainstream SUVs due to its luxury branding, advanced technology, and higher repair costs in the event of an accident. Factors influencing your premium will include your driving record, location, coverage levels, and the specific trim level of the GLS you choose. It’s always recommended to obtain insurance quotes from multiple providers before purchasing.

Potential Considerations

While the 2017 Mercedes-Benz GLS is a highly desirable vehicle, there are a few potential considerations buyers should be aware of:

• Fuel Economy: Given its size and powerful engines, the GLS is not the most fuel-efficient vehicle on the market. The V8 models, in particular, will consume more fuel, especially in city driving. This is a common trade-off for the performance and luxury offered.

• Third-Row Space: While the GLS offers a third row, it is best suited for children or smaller adults on shorter journeys. Adults may find the space somewhat limited for extended periods, especially in terms of legroom and headroom.

• Complexity of Technology: While the technology is advanced and beneficial, some owners may find the sheer number of features and settings in the COMAND® system to be initially overwhelming. Familiarizing oneself with the owner's manual or seeking assistance from a dealership is recommended.

• Ride Comfort vs. Sportiness (AMG): While the GLS offers a comfortable ride, the AMG GLS 63, with its performance-oriented suspension, can feel firmer than the standard models. This is a deliberate choice for enhanced handling but may be a consideration for those prioritizing ultimate plushness above all else.

Overall Summary

The 2017 Mercedes-Benz GLS stands as a formidable contender in the full-size luxury SUV segment. It masterfully blends opulent comfort, cutting-edge technology, and potent performance, offering a truly premium driving experience for families and discerning individuals. While its fuel consumption and third-row space are typical considerations for its class, the GLS delivers on its promise of refined luxury, advanced safety, and impressive capability, making it a compelling choice for those seeking the ultimate in a German luxury SUV.
