Summary
With 140 currently listed for sale near Houston, TX and an average price of $76,000.00, 28.6% 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.
90.7% of 2021 GLS models on CarGurus are accident free.
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.
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. This model offers multiple powertrain options, including a powerful twin-turbocharged V8 in the GLS 580 and the AMG GLS 63, which delivers exhilarating performance. The GLS-Class is designed with comfort in mind, boasting spacious seating for up to seven passengers and a cargo area that outshines many competitors. Notably, the GLS features the MBUX infotainment system, which includes a massive touch screen and voice control capabilities, enhancing the driving experience. While it excels in luxury and technology, potential buyers should be aware of its cramped third row and less-than-ideal fuel economy.

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.
