My opinion, too old to bother with and so many miles. There are lots of luxury SUV's like that out there for very very little money now a days, and don't have high miles.
I understand a LC is something a little more special, but parts are very dear on those (I think, we have a Toyota Hilux turbo diesel and prices are killer when they still exist). Very large potential for high repair bills (or walk away).
The 300TD is almost as good as it gets for road trips (been coast to coast with them) if the seats are proper and everything sorted, better highway tourer then city runabout.
If you like highway rides and all wheel drive look at an Audi A8, never rust and very nice on the highway with very cheap buy in.
