pretty much all atcs and atvs have some kind of tool box but that is a rare find take those and put them some where safe they are worth alot of money. Same kind of thing happened when i got my XL250 i was just messing around and i opened the helmet lock to make sure it was working and there was a black cover cliped to the bottom of the seat pulled it open and there was the original owners manual in realy nice shape.
