This is something I discovered a few years back, and I thought of it as I read the post about replacing a center console. Others might benefit from my "system." Yes, those plastic interior parts do break and crack. What you do is, for weak areas(i.e. console tops, door pockets, etc.), or areas that have already developed cracks, but are still intact, use a combination of expired plastic credit cards and five minute epoxy to repair/reinforce such areas. Just cut the card to fit the area/space, apply the two part epoxy according to directions, push the cutout repair piece behind the area you need to reinforce in a manner so that it does not show, and let it cure. You're done, and the area is now much stronger than before. I probably have about six square feet of such material in my old 300k 740 -- but the plastic still looks good!
