What to Expect

Owning a 2018 Mercedes-Benz GLS is generally characterized by a premium and comfortable experience. The vehicle's robust engineering and high-quality materials contribute to a lasting sense of luxury.

• Maintenance: As with most luxury vehicles, scheduled maintenance is crucial for keeping the GLS in optimal condition. Expect regular oil changes, fluid checks, filter replacements, and tire rotations. The cost of maintenance can be higher than for non-luxury brands, reflecting the specialized parts and expertise required. It's advisable to find a reputable Mercedes-Benz dealer or a qualified independent mechanic specializing in European vehicles. For peace of mind, consider extending the warranty or exploring maintenance packages offered by Mercedes-Benz.

• Insurance: Insurance premiums for the GLS will likely be higher than for a standard sedan or smaller SUV due to its luxury classification, powerful engines, and advanced technology. Factors such as your driving record, location, the specific trim level chosen, and the chosen coverage levels will significantly influence the cost. It's recommended to get quotes from multiple insurance providers to find the best coverage at a competitive rate.

• Typical Ownership Experience: Owners can expect a smooth, quiet, and powerful driving experience, with a refined cabin that insulates occupants from road and wind noise. The advanced safety features provide a sense of security, and the versatile interior seating and cargo configurations make it practical for various lifestyle needs. The GLS is a comfortable cruiser, adept at long-distance travel.

Potential Considerations

While the 2018 Mercedes-Benz GLS excels in many areas, potential buyers should be aware of a few aspects:

• Fuel Economy: The powerful V6 and V8 engines, coupled with the vehicle's substantial size and weight, mean that fuel economy is not a strong suit. Owners should anticipate higher fuel consumption, especially in city driving. The GLS 450 will be the most fuel-efficient option, while the AMG GLS 63 will naturally consume more fuel.

• Infotainment Complexity (Initial): While the COMAND® system is feature-rich, some users may find it has a slight learning curve initially due to the sheer number of functions and customization options. However, most drivers adapt quickly to its interface.

• Third-Row Seat Space: While the GLS offers a third row, it is best suited for children or shorter adults on shorter journeys. Adults may find legroom and headroom somewhat limited for extended periods, which is a common characteristic of most three-row SUVs in this class.

• Ride Firmness in AMG Models: While the AMG GLS 63 offers exhilarating performance, its sport-tuned suspension can result in a firmer ride compared to the GLS 450 and GLS 550, which might be noticeable on rougher road surfaces.

Overall Summary

The 2018 Mercedes-Benz GLS is an exceptional full-size luxury SUV that masterfully blends opulent comfort, powerful performance, and advanced safety features. It provides a commanding presence, a spacious and refined interior, and a driving experience that is both serene and engaging. While fuel consumption and the practicality of the third row for adults are aspects to consider, the GLS remains a compelling choice for those seeking a premium, capable, and feature-packed vehicle to transport their family and conquer the road with confidence and style.
