Some things that I can suggest (not all are serious as this seems to be a first-world problem):
- Buy a blue 3 and make sure that you register the VIN with Tesla
- Figure out how to, or see if somebody has already, hack the car's software and change the car's image there
- Ask Tesla if it's possible for them to change it. Note: the blue that they have as a standard car color may not match your wrap
- Relax and enjoy the car
edit: Googling around says that the third item is probably the one you should pursue. A couple of older threads here and elsewhere says it can be done if you ask the Service Center. Be prepared to fork over some loonies.
