Hey Ewald, that's an interesting point raised.
Purchase, then TWO rebuilds covered by insurance. I imagine that was helpful to the 3G bottom line!
It is of course possible that you sold the plane at the price it cost you, and that you only asked the insurance companies to cover the costs on the rebuilds (no margin).
Possible, but unlikely, I would suggest. However, until I know what you were paid and what it cost you - I'm unable to judge.
