Actually, I think the best part is the engine. With a mid-time engine,
you've got a crap shoot. The bluebook/Vref/whatever says the plane is
worth $X, with the engine prorated for how many hours it's got on it.
Maybe it'll make it to TBO, maybe it won't. With a dead engine, you can
negotiate from a point of view that it needs a new engine right from the
start, and work that into the offering price.

I'd much rather buy a plane with a run-out engine and budget for an
immediate engine replacement/overhaul. That way at least you know what
you're getting.
