The key may be the "properly taken care of" part (or they didn't buy crap at the time part).
I live in a greater than 200 year old house and all the older windows dating to whenever are complete crap compared to newer Andersens I've had installed.
Survivorship bias. The cheap stuff doesn't last. "Take from the dresser of deal, Lacking the three glass knobs, that sheet..." - Wallace Stevens, 1922. "Deal" being cheap pine or other soft heartwood (in the poem he is trying to evoke a scene of poverty and maybe a bit of gaudiness). Not that buying old can't be an excellent strategy, it having survived either a long life, or perhaps it was just never used in which case all bets are off.
