Is anyone else stockpiling parts?

Your not alone. I just upgraded my factory Nav/radio unit,speakers and amp because the factory amplifier went out on me. The factory Bose system rocks. When I upgraded I ran new wiring and kept all original wiring intact. Even though I spent about $2500 on a new system, I bought another brand new Delco amplifier so I could put the original system back together in the future. So far I've stocked up on a OEM front carpet, OEM drivers side bottom leather seat cover, and air suspension compressor. If anyone knows of anything that is bound to go that we should get a back-up of list here please.
