Open it up, check to make sure nothing is missing or warped/broken. If it's a kit that is new to me, I'll spend extra time checking out the instructions, body, etc. I always seem to want to set the body/interior/chassis together. Then I'll assign it an inventory number, enter it into the spreadsheet, make some notes as to how I want to build it, put it into the to-build closet. Periodically, I empty the closet by packing kits into 14x14x16 storage boxes (8-10 per box) which go off to the storage unit..
