Summary
With 880 currently listed for sale and an average price of $49,835.00, 33.1% of 2021 Mercedes-Benz GLS models for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 Mercedes-Benz GLS 4.67 / 5 stars.

The 2021 Mercedes-Benz GLS-Class brings a new level of luxury to full-size SUVs, featuring three rows of spacious seating and impressive performance options.
Why it stands out
The 2021 Mercedes-Benz GLS-Class is often referred to as the S-Class of SUVs, and it lives up to that reputation with its luxurious interior and advanced technology. With three rows of seating, it comfortably accommodates families while providing ample cargo space, making it a practical choice for those who need room without sacrificing luxury. The GLS offers multiple powertrain options, including a powerful V8 in the GLS 580 and the high-performance AMG GLS 63, which can accelerate from 0 to 60 mph in just 4.1 seconds. The vehicle is equipped with the latest MBUX infotainment system, featuring a massive touch screen and voice control capabilities, enhancing the driving experience. However, some users have noted that the third row can feel cramped, and the technology can be unintuitive at times. Overall, the GLS-Class stands out for its combination of comfort, performance, and cutting-edge features.

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.
