Honestly you are better off finding another ML with the 3rd row already installed. The ebay seats wil almost always not come with the seatbelts or the consuls that mount to the truck. The seatbelts are around $200 a pop and the consuls are not available. Add this to the $500-$800 ebay seats and you still can't install them due to the missing consul. The third row was discontinued by Mercedes so getting new is not an option.
