Can we agree on this?
Old does not necessarily = tired (e.g the 207 you mention, sounds like a nice a/c)
Tired does not necessarily = old (e.g. I have flown aircraft less than 5 years old with lots of hangar rash, big wear & tear)
Tired = does not deliver the expected performance, maybe through poor maintenance, maybe because the wear and tear has accumulated over time, like Big Pistons Forever says.
