2 wd surf???

[DAVEGREENAN]

I am looking at a 3.0 surf 1993, looks very clean but comes up as a 2WD on the vehicle check.
The owner says ithe 4WD was disengaged during the import but all the working parts are there.

Does any have any experience of this?

How costly/difficult would it be to re engage the 4WD system?

New to forum so appreciate any feed back offered.

Thanks
