I am looking for information and potential rarity of multiple lego sets all themed ferrari F1 racers 8386+8375+8362+8389, the sets themselves i know the value and rarity but i have a large (53x53x73cm) promotional official lego box that has the four sets images on the outside of the box (built images), i have asked AI and they have suggested it is very rare to have the large promo box. AI also suggested the promotion was offered via toys r us around 2005, any ideas of it's rarity as a complete set or perhaps the box alone as the sets inside can still be bought at an inflated price.
