I just found this suv 3rd row seat website for sale and wondering whether these extra row seats be fitting with the Niro cargo space perfectly if we mod it. This will be great idea if there is a small bench seat for children in the Niro. All Niro model has plenty extra under cargo floor space so I guess a little modification for extra small 3rd row seat wouldn't be problem for us. If we could done it, then this will be the first crossover car with third row seat.
