Why it stands out
The 2021 Mercedes-Benz GLS sets itself apart in the competitive full-size luxury SUV segment, being often referred to as the "S-Class of SUVs." With a strong emphasis on comfort, the GLS-Class comfortably seats seven, with plenty of room in the first two rows and acceptable space in the third. Its available engines include a 3.0-liter inline-six and a more powerful 4.0-liter V8, catering to those who crave performance alongside luxury. The GLS also showcases a cutting-edge infotainment system with a large touchscreen interface and voice control features, making it tech-savvy. While it is a big vehicle, its thoughtful design gives it an unexpectedly nimble feel on the road. However, some drawbacks include a cramped third row and a somewhat steep fuel economy. Overall, this SUV strikes a balance of luxury, performance, and practicality, making it a top choice for families seeking sophistication in their travels.

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.
