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.
