Yes, I often do. Having spent a quarter century in the military, I moved every 3-4 years and built kits normally went into a box and got banged around, missing parts, getting broken,etc.
Every so often, I'll crack open one of the boxes to grab something to use for another project. Almost invertably, I end up grabbing an old, beat up kit and after fishing some of the bits & pieces out of the box, I'll rebuild it, repaint it and redisplay it.
