Why it stands out
The 2020 Mercedes-Benz GLS sets itself apart as the roomiest vehicle in the Mercedes-Benz lineup, seamlessly merging the luxury of the S-Class with the practicality of a three-row SUV. With seating for six or seven and up to 94 cubic feet of cargo space, the GLS is designed with families in mind without sacrificing the high-end feel typical of the brand. This model marks a notable improvement over its predecessor, offering a new six-cylinder engine with a mild hybrid system that enhances efficiency and performance. Standard high-tech features, including dual 12.3-inch displays and comprehensive safety measures, further enhance its appeal. However, while the GLS excels in comfort and space, some users may find the third-row seat access and touch-sensitive controls less convenient.

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.
