Mercedes GLS Review: Is the Quality Actually This Bad?

Mercedes GLS Review: The ultimate luxury 7-seater or a missed opportunity? Mercedes calls the GLS the "S-Class of SUVs," but does it actually live up to that legendary name? In 2026, with rivals like the BMW X7 and Range Rover getting even better, we’re finding out if the GLS's latest facelift is enough to keep it on top. From the gargantuan 5.2-meter footprint to the controversial "fake" exhausts, I’m digging into every detail of this £110,000 behemoth. I’m checking if the third-row seats are actually big enough for adults, and asking why some of the interior plastics feel more like a C-Class than a flagship. Is this the best way to move seven people in luxury, or should you look at the BMW X7 instead? Let’s find out.
