At the end of October 2012 we traded in my wifes 2008 Mercedes 4matic (station wagon) for a new Mercedes 2013 GL550.
We love the exterior design of the car and the flexibility on the interior design with the third row seats.
The acceleration of the car is incredible-no problem merging onto the freeway or passing.
Gas mileage is not the cars strong suit but I did not expect it to be.
Now the bad, at 4000 miles the car needs new front rotors which are not yet a stocking item at my dealership-10 day wait! A In addition both side view mirrors are defective-drivers side is frosted and the passengers side has two stripped bolts off its backing plate.
Engine and third row seats.
Improve the reliability of the car, stock parts at the dealership!
Also I find the electric steering to be numb-kind of like driving my fathers old 1971 Oldsmobile Tornado!
