I would love to see an APU in it, but my guess is less than 50 percent on that one. As far as changing the avionics- I put that at less than 10 percent. Embraer has had enough issues with computer glitches in past models that I would really hope we just let them iron out whatever glitches this one has in the next couple of years before any are delivered with a whole new set of potential glitches.
