Set looks 100% complete.  I assembled the set per the instructions to check its condition and completeness.  It appears all the parts are there, with no broken parts that I could see.  The tabs look in great shape as you can see from the pictures as I documented as many as I could.  The elevator support columns were only set in the slots for the pictures as I did not want to snap everything together so it would be easier to disable.  A few of the stickers are starting to peal up a bit from age.  The mat is included and in great shape, the original instructions are included along with the original sticker sheet with some unused stickers still attached.  Please look over the pictures as they are part of the description.
