Just a fantastic SUV. Extremely comfortable and handles great. The biggest issue is just awful gas mileage. Maybe 10/12 in the city if youre lucky.

Amazing vehicle and owning a Mercedes is on a completely different level than most cars, SUV’s and trucks on the road today. Great experience. The only negative is they are not cheap and depreciation after 40k miles is accelerated. But in my opinion, it’s worth every penny.

Lacking new and improved electronics and navigation systems. Other than that it is a great model year.

The X166 GLS63 is one of the best cars in its class on the market. The proven M157 Biturbo V8, 722.9 7 speed transmission provide excellent drivability weather cruising, towing, or when enjoying its 577hp. From the AMG massage heated and ventilated seats to the Bang & Olufsen sound system the interior is well dressed and ready for long road trips.
