Who has kept all their OEM parts after installing performance mods & is it worth it?

Hey everyone - just wanted to know who has kept all their oem parts for their Z instead of chucking them for next to nothing. In this economy, I don't see many buyers wanting to buy our modded Z's at a higher price than buying a stock one at the dealership, so is it smarter to keep all the oem parts and sell it back to a dealership later on or is it not worth it after you put into consideration all the time and money it takes to take it all off and put back the originals? Curious to see what you guys think.
