Why it stands out
The 2021 Mercedes-Benz GLS redefines luxury in the full-size SUV segment, drawing comparisons to the flagship S-Class sedan.

The GLS comes equipped with an advanced digital cockpit anchored by the MBUX infotainment system, offering enhanced connectivity and user-friendly controls. Under the hood, buyers can choose from various powerful engine options, including a twin-turbo V8, providing a performance punch that is rare in its class.

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.
