Does anyone have a picture of the vario boot floor on a superb and once the seats are folded is it compleatly flat or is there a small lip once seats are down.

I think there is actually a photo on the main Skoda web site at the foot of the main superb estate model page.

This is the variable boot floor in its upper position with all seats down: 

 

Does anyone know if you can buy the vario boot floor as a separate aftermarket item to fit to a superb that doesn't come with it? I have ordered the SE L Exec estate and I don't think it comes as standard. 

If so any idea of the part number? Presumably i could order from TPS with the part number...?
