Only a tiny question, but something I've always wondered
What the three grooves were for on inside bit of the rear arm rest.
I know the two front circular bits are shallow cup holders, and the bit in the centre to be used as a table, but haven't worked out what the grooves are for in the top part, pens maybe? but i can't get any to fit and stay in place.
Here is a picture of the part I am talking about:
Does anyone know?
Thanks
