I open everyone I get, just to make sure it is not damaged. I also separate the parts so bodies don't warp, tires don't touch anything else,decals, windows and anything else does not get damaged. I think we become collectors by default. Most of us buy with the intenion to build everyone we buy or use parts from a kit . When we get older and have a few hundred kits, that's when we know we have a sickness called plastic dependency. Without new plastic to smell I would fade away.
