overall
Summary
With 932 currently listed for sale and an average price of $49,929.00, 35.4% 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.
82.8% of 2021 GLS models on CarGurus are accident free.
The 2021 Mercedes-Benz GLS is renowned for its luxurious interior, spacious seating, and impressive technology features, making it a top choice in the full-size SUV market.
Why it stands out
The 2021 Mercedes-Benz GLS-Class defines luxury among full-size SUVs, seamlessly combining style, performance, and comfort. It is essentially the SUV equivalent of the S-Class sedan, offering three rows of spacious seating that prioritizes passenger comfort, even accommodating adults in the third row—something many competitors struggle with. Its interior is equipped with advanced technology, like the MBUX infotainment system, providing an aesthetically pleasing and user-friendly experience. Performance-wise, the GLS offers multiple powertrains, including a powerful twin-turbocharged engine, ensuring plenty of power when needed. However, it also faces challenges, such as a cramped third row and subpar fuel efficiency, which some buyers may need to consider. Overall, the GLS effortlessly blends practicality and luxury, appealing to those who desire both style and functionality in their vehicle.

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.
