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.

Reviewed a 2020 Mercedes-Benz GLS on Sep 1, 2024
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.

Why it stands out
The refreshed 2024 Mercedes-Benz GLS stands out as a large three-row luxury SUV that leans into the brand’s upscale image with finesse. It brings minor styling modifications, fresh colors and trim, more standard equipment, enhanced off-roading technology, and a new version of its MBUX infotainment system for 2024. Those updates build on an already appealing luxury vehicle and help make the GLS feel current without losing its core identity.
What makes the 2024 Mercedes-Benz GLS especially appealing is the way it combines comfort, premium interior materials, and easy-to-use technology. It is also presented as a vehicle that can satisfy buyers across the GLS 450, GLS 580, AMG GLS 63, and Maybach GLS model series, though the price of entry is steep. The main drawbacks are practical ones: the AMG Line Package impedes entry and exit, third-row seat access is a challenge, and touch-sensing controls may not be to everyone’s liking.
