I bought this a few years back with the intention of building it with my son. Sadly as he is getting older so are his interests & Lego's are not one of them anymore. This box is still factory sealed & has been stored in a smoke-free home. I paid $400, I'm selling it for $350. I prefer to deliver/pick up because of it's size. Will ship for $30 to the lower 48 States. Any questions just email me at email@example.com for faster response. If paying with PP, please send as "gift".
