there are a few 461s in PK and only a handful of 463s, most of the 461s are abused but almost all the 463s are used by embassys and our VVVVVIPs. almost all the 463s are armoured or bullet proof (all are 500s or 420CDI). the 461s are 230s or 300Ds mostly.
there have been many attempts to restore them but they have all failed miserably by fitting toyota or mitsubishi parts (specially interiors and engines).
good luck on your search though, you might uncover a gem somewhere which we don't know about.
