Love it, but I do have a small issue.
The car looks great and the seats are very comfortable. Performance is excellent, but I do not care too much for that stuff. The only issue I have is that the computer is suggesting me to go get service a even though I just got it, and it bothers me. Overall, I love the vehicle.

Reliable, comfortable, and durable.
My Benz is very reliable and comfortable. I enjoy the fact that it brings me minimal cost as the product are strong enough to take any destination. I feel like a home in it most of the time. The music box is top notch. I most time need to cover a long destination this I do by speeding through a free run way. The speeding is fantastic as well. Never had the experience this ride is giving me before.

Luxury driving in a roomy SUV.
High end luxury SUV that is truly comfortable to drive! I love all the luxury features such as the mb-tex interior seats which look and feel like real leather but do not show the same wear and tear over time. Handles beautifully, drives quietly and with great pickup for the highways. The interior space has been well-thought out and offers plenty of room in all 3 rows of seats. When desired, back rows of seats are easily lowered to expand trunk space. On the downside, gas usage is expensive, as it uses premium (91 octane minimum) gas and highway mpg is low. Also, once your car is out of warranty, repairs are expensive.

Things I love about my Mercedes.
I love everything about it except cost of maintenance. Ride is quiet and very comfortable. The outside is very attractive and sporty. It turns on a dime and parking is so easy. The cameras on the vehicle are right on and help with parking and reversing.

Amazing! Logo lights and heated/cool air seats!
So far the vehicle is amazing, even though it is a big SUV the drive is so smooth and light, does not make it seem like your driving that size vehicle. The modes of driving are also spectacular! When you shift drive modes you cannot even feel the change. The spec are also something else, the elegance within every detail is amazing! Even the dealership treats you amazing with all the perks of Starbucks coffee and treats!

Gls450 Mercedes Benz 2018.
Very smooth and you can barely feel the bumps. The CarPlay is kind of annoying because it always reads the messages aloud and connects even when you do not want it to. The seat heaters last a long time. The car is very reliable and comfortable depending on which mode you put it in. There is luxury, comfort, sport, etc.
