overall
Summary
With 888 currently listed for sale and an average price of $49,656.00, 37.4% 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.
83.1% of 2021 GLS models on CarGurus are accident free.
The 2021 Mercedes-Benz GLS boasts a spacious interior with three rows of seating, luxurious features, and impressive technology, appealing to buyers looking for a full-size luxury SUV.
Why it stands out
The 2021 Mercedes-Benz GLS is often regarded as the S-Class of SUVs, offering a remarkable blend of luxury and performance. This full-size SUV comes equipped with three rows of spacious seating, emphasizing comfort for all occupants, making it suitable for families or those who frequently transport multiple passengers. The GLS is powered by various engine options, including a robust twin-turbocharged V8, delivering not only impressive power but also a seamless and engaging driving experience. Its tech-savvy interior features the new MBUX infotainment system, a massive touch screen, and advanced driver assistance systems, which enhance both usability and safety. Although the GLS excels in many areas, potential buyers should note the cramped third row and the vehicle's relatively poor fuel economy, especially in the more powerful AMG variant.

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.
