So guys im buying some lego with the purpose of keeping it brand new and sealed and unused to sell for a profit about 1 or 2 years afters its discontinued. Would opening the box decrease the value? I assume it would but then i think of what if the box is missing people and you sell it to somebody after its been discontinued and they cant get replacement parts or instructions from lego anymore? Could it somehow be smarter to build the lego once then bag it up again just to ensure everything is there? If anybody has experience in this please let me know your thoughts and what i should do. Thanks
