CarGurus Analysis: 2021 Mercedes-Benz GLS
overall
Summary
With 822 currently listed for sale and an average price of $48,902.00, 36.0% of 2021 Mercedes-Benz GLSs for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 Mercedes-Benz GLS 4.67 / 5 stars and CarGurus experts gave it an 8.33 / 10.
84.1% of 2021 GLS models on CarGurus are accident free.
Why it stands out
The 2021 Mercedes-Benz GLS is positioned as a luxury-first full-size SUV, and its appeal starts with the way it blends three-row practicality with a premium feel. Mercedes ties the āSā in its name to the S-Class flagship sedan, and the GLS is presented as the āS-Class of SUVs,ā which captures its emphasis on comfort and refinement. It also offers spacious seating for three rows, along with enough cargo room for groceries, weekend bags, and even larger items that would be difficult to fit in a sedan.
What makes the 2021 GLS distinctive is that it does not stop at comfort alone. The available performance is described as surprising, and the SUV is credited with multiple powertrain options, plenty of cargo space, and impressive technology. At the same time, it is not without drawbacks: the third row is cramped, the technology can be unintuitive, and fuel economy is poor. That mix makes the GLS appealing to buyers who want a high-end, full-size SUV with strong luxury credentials, while still accepting some compromises in usability and efficiency.

I feel that the features listed for this vehicle is good. I just didnt see one option that would have made me buy the vehicle fast. I did not see the multi contour massage feature. I wished that it would have been made clear on the listing.
