Boot Tray
Available from Nissan for a price of £97 back in 1991 the Rear lower Boot Tray was an Optional Extra. You can see that it has compartments which were created to accept optional items such as the Figaro Car Set, Car Cover and maybe a foldable breakdown triangle? The tray capacity is 560mm wide x 640mm deep x 90mm high.
What goes where?
Where can I buy one?
If your car does not contain a tray it maybe worth trying to buy one as it does add much needed storage. They are no longer available from Nissan but do come up for sale on Ebay or Figaro Trader
