Agree ^^^ I have owned two Liberty's one gas and the diesel version... they do some what well off road, but they have a very limited and expensive aftermarket and they are not all that reliable, especially the diesel. They are uncomfortable, the seats suck and the interior cloth get stained by even water. You would think they would be roomy, but they are not very roomy. Sounds like the one you are looking at could have t-case problems but more than likely the linkage to the shifter needs adjusting...
What do you mean by well outfitted? What are your plans for the vehicle? If you are planning on modifying it look up jeepinbyal and rock lizard they are they only ones who make decent parts for the Liberty.
