Amazing suv for people who want a small SUV. Size of a Nissan Rouge, but with the features and luxury options of a Mercedes.

Fit and finish is what you would expect from Mercedes. The front seat comfort is a true relief for my aching back. Everything inside is focused on convenience for the driver. The track pad, mouses, and other interactive features make sure that everything is literally at your fingertips. The interior lighting is soothing as well as functional, especially when you have middle aged eyes that don’t see quite as well in the dark as they used to. The panoramic sunroof makes it feel like you can see the whole sky giving the car a very open feel in the front. Plus, the ceiling height is generous enough to easily fit my very tall sons. There really isn’t anything about this vehicle that I dislike except the standard floor mats. I’ll be ordering all weather mats. I do feel like there are some features that should be standard rather than optional for a luxury vehicle, but fortunately this one already had everything I needed. Also, the Denim Blue is a rich and velvety color. I had my mind set on black or dark grey initially, but I am glad that the blue was where I landed. It’s gorgeous!
