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 high-performance AMG GLS 63 variant. The GLS-Class is designed for comfort, boasting spacious seating for up to seven passengers and a cargo area that outshines many competitors. Notable features include the MBUX infotainment system with a massive touch screen, voice control capabilities, and a suite of driver-assistance technologies that enhance safety and convenience.

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.
