The GLS is beautiful, fun to drive, extremely comfortable, and solid. I only wish the running board was 1 or 2 inches wider. As it is it makes ingress and egress difficult.

The redesigned GLS is truly a spacious, luxurious SUV. The 450 has plenty of power and refinement for totally enjoyable driving. The turning radius is extraordinary, and makes for easy parking. Drives smaller and more nimble then it’s size. So far, I’m very happy with this SUV. I upsized from an Audi Q7 and while I loved my Audi, this size was a better fit. Well done Mercedez. UPDATE: after driving this great SUV for a year and a half, I still love it. I’ve had no issues or problems and have only done normal maintenance. I’m very happy with the 450 GLS.

Well let me tell you. I bought this ride in March 2020. I’ve put on 12,000mi (20,000km) in 6 months. The rear tires are bald, un-drivable!. Already very upset until I was given a quote for new rubber. How does $3500cdn strike you! What! At this rate I need to replace my tires twice a year for my cost of $7,000 a year in rubber But wait. I love in Canada. I need all season tires. Nope. They only make Pirelli Pzero tires for this rim. Ok. No all season. Winter tire&rim pkg. Yup. $6,000 fir a set of winters. Great deal. Don’t forget you can only drive those half the year still need to replace my Pzero’s after every summer! Ok. Let’s put the factory 21’s on it.

** Update 4/23 Well, this Mercedes is also plagued by stinky HVAC like my 2017. I am not sure why Mercedes cannot get this under control. We have owned many other makes and have NEVER had this problem with any except Mercedes. This is my third MB SUV. I previously owned a 2017 GLS450 and a 2013 GL350 diesel. I would buy another diesel if they still made them but of the gas models, this one is best. The issues I have are first, with the black plastic around the wheel wells. I hate that, it looks like something that would be on a Honda Pilot. I realize I could avoid that by getting the 580 or the AMG model but I did want to spend $30+ grand to avoid some chepo plastic, I shouldn't have to. Hopefully that goes away with subsequent models. The other issue, I had with my 2017 also, is stinky air conditioning system. Mercy, it smells like gym socks. There is a class action lawsuit for the 2017 so hopefully that will compel them to come up with a fix and apply it to the new ones too. It smells like a new vehicle when it's cool and a locker room when it's hot. An $80k+ vehicle should not have this issue. Apart from these two things, the car handles and drives great for such a big vehicle. It hauls all that we need and the V6 has sufficient power. My husband drives an AMG GLE and it's quicker but the power mine has is sufficient for me. I agree with the previous reviewer about the Driver Assistance package and the massage seats. Great additions especially for road trips. I have had it a year and it has functioned properly the whole time. If Mercedes gets rid of the black plastic and figures out how to keep their AC fresh, I will buy a fourth when I am ready for a new vehicle.

It took me almost a year to make a decision on a new suv. I’ve looked at BMW, Porsche, Volvo, Audi, etc. I was paralyzed by analysis. I’m so glad I went with GLS. It’s my first time owning a MB. Even though it’s a large SUV, it’s very easy to drive. I love the comfort and the handling. MBUX is awesome. I love finding different options on it. I’m a believer in MB now.
