Sadly its not about quality of repair but STIGMA and it is several years not one before that aircraft will close the gap again.
Pace, it doesn't have to. If you buy it a discount to the market of, say 30% and then sell it on a couple of years hence with the same discount (or potentially less), then it's effectively a zero-sum game. You bought below market and re-sold below market. In A&C's scenario you might even be quids in if holding the a/c for long enough.
