Buy a new one, right away. You know that.
As for the "finished" bike: Consider a custom paint job. Maybe look up some parts prototypers and have some one-off custom pieces designed and fabricated---stuff no one else in the world will have.
If absolutely everything else fails: Ride it until some part wears out, and then buy the newer, shiny, lighter, but possibly in no way better "latest development."
It is a sad day indeed when a person with a perfect bicycle is reduced to actually riding it. My heart bleeds for you.
