They're nowhere near life expired. There's no reason why a partial replacement and doubling up the remainder wouldn't work, along with the refresh discussed in this thread! Totally agree that they're not suitable for local services. I don't think they'd see the long-term use like HSTs have or anything like that, but they'll be in use for a good 15 years more, at least.
They're not life expired, but they are of a very poor overall design - toilet issues, internal system reliability issues (particularly reservations), very worn interiors (so you'd at least want to replace the seat frames), very inefficient interior layout, polluting older diesel engines, diesel under the wires etc.
They would be vaguely workable on Liverpool-Notts (but 185s would be better) or on the North Wales Coast (but Mk4s would be better)...beyond that, a modern bi-mode would be far more use and based on recent figures not necessarily cost all that much more to lease.
