I have just sold my 14 year old 300Tdi Disco with 222000 on the clock.
A real meccano set, in the 160k I put on the clock only failed to make its destination once, when the clutch arm went after 180k (snapped with metal fatigue).
Spares are dirt cheap, both new and SH now, do not expect 100% reliability, but they are robust workhorses, most things can be fixed with your average tool kit.
Still popular regardless of condition, I just sold mine for far more than expected, and plenty of punters seeking one.
Watch out for rust, that is the killer, Sills, rear arch panels inside rear doors and boot floor
