Why it stands out
The 2020 Mercedes-Benz GLS excels as a midsize luxury SUV by combining the opulence of the S-Class sedan with ample space and functionality. Its three-row seating accommodates up to seven passengers, making it ideal for families or those needing extra room for passengers and cargo. The stylish design is matched by a comfort-focused interior featuring premium materials and advanced technology, enhancing the driving experience. Noteworthy engineering continues with the GLS450's robust 3.0-liter turbocharged inline-six engine, providing both power and improved fuel efficiency. Safety features are comprehensive, including blind-spot monitors and an advanced 360-degree camera system, ensuring peace of mind on the road. While the GLS shines in comfort and capability, some may find access to the third-row seating and pointy touch controls for infotainment a bit cumbersome, highlighting areas for improvement amidst its many strengths.

Love all the features and it can pull my camper no problem! Beautiful car with kinetic seats that are nice when on a long drive. Love how my phone integrates into the dash screen. It’s classy for business but heavy enough to be outdoorsy as welll. Great value and you can’t go wrong with a Mercedes.

I just purchased a 2020 GLS 450 with 18,000 miles on the clock and I LOVE it. Nothing beats Mercedes when it comes to quality of vehicle and service from the Mercedes team. I was able to get an extended 5 year/ 100,000 mile warranty, which to me was worth the extra money. My last Mercedes was a 2003 E 500. It was such a good car that I waited this long to replace it. That’s what you get when you buy a Mercedes.
