Hi all,I have a Panda 1.2 MyLife Dynamic, without a split rear seat but with the 5th seat belt.I have tried many times, but when I fold the back seat down, it never goes flat (ie horizontal), there is always a slight incline. This makes it a bit difficult when loading (though not impossible).Is this normal or am I not doing it correctly? Is there a knack to it? The sit down part doesn't seem to lift up or slide forward as in some cars.Thanks.
