About the 2017 Mercedes-Benz GLS
With an overall Carivo score of 6.8/10, the 2017 Mercedes-Benz GLS earns a Good rating among the suvs we've scored. Its strongest dimension is Safety at 8.3/10, while Value at 5.7/10 is where it trails the competition most noticeably. It's a capable but unexceptional suv — stronger alternatives exist if you're willing to shop the segment carefully.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. We rate reliability at 5.9/10 — below the segment average in our scoring. Budget for potentially higher maintenance costs and check the recall record below before buying. On safety it earns 8.3/10: respectable, if not class-leading — several competitors bundle more driver-assist tech as standard. Check your trim's official ratings at nhtsa.gov.
Performance at 6.7/10 is a genuine liability and a score that should factor heavily into any buying decision. The powertrain and chassis dynamics trail class rivals by a meaningful margin — don't overlook it. Technology scores 8.2/10 — one of the stronger tech packages in the segment. Expect a responsive infotainment system, broad smartphone integration, and a solid suite of driver-assistance features.
Priced from $65,372–$84,858, 14 MPG, seating 7, the Mercedes-Benz GLS sits in the luxury tier of the suv market. The value score of 5.7/10 is a red flag — comparable alternatives offer meaningfully more for the same outlay. Shop the segment before deciding. At 9 years old, resale value, parts availability, and whether a successor model has improved on its weak points are all worth investigating before committing.
Bottom line: There's a case for the 2017 Mercedes-Benz GLS, but it needs the right buyer. Its performance and reliability and value scores trail the class, and several higher-rated rivals sell for similar money — comparison-shop before committing.
