Good experience in dealing with Kerron at dallas lease
Good experience in dealing with Kerron at dallas lease returns, would Definitely buy another vehicle from him !
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.

The dealership was clean compared to other places we visited and their customer service is top notch. I would definitely recommend this place for any buyer who wants a no pressure purchase
Love it so far
Special. A delight to drive. Love the way it handles. Extremely responsive, both acceleration and steering. Cabin is very quiet and at night almost too relaxing.

Large yet stylish enough to carpool the Grands
We just bought this car. Comfortable, roomy, easy to drive. Not quite a luxury ride that the Lexus GL has but performs well. Takes a second to get comfortable with the bells and whistles. Beautiful car, 2 2 2 seating. Easy for kids to get in without climbing over or moving a seat. We bought this SUV for me to drive around town as well as to school carpool my grandchildren. So far...very pleased. This is my third Mercedes. My only complaint with Mercedes is the fuel tank on the passenger side. I feel a little more vulnerable being on the opposite side of the driver side when pumping fuel. I assume it has been this way for years. I guess safety at the gas station was not as big of a concern as it is today. If considering a luxury SUV test drive. I think you will be pleased/
