Another idea I've found in order to solve
the lack of space for item in my +4 :
I've bought 3 "vide-poches" in a Longchamps
shop.
2 are located in front of the seats behind the
galvanised cross member, the other one is located
behind the gear lever.
They are made of fine leather with press buttons
and exist in many colors, easy to combine with the
leather of the interior.
And, they are cheap (30 euro each..).
It's looking fine and seems to be genuine.
Best regards.
