and so far the 4x4 that fit in that rage are the 1999 Jackaroo U8 Olympic Edition ( 3.0 diesel ) and 2000 Land Rover Discovery TD5 ( Diesel ).
I have read in other forums that Land Rover is quite expensive to maintain here in Australia ( Cost of Parts ) , but if you could source out the parts online overseas that will fix the problem.
...About the Jackaroo, I have learned that there are some issues with its injector....which makes it very expensive to fix
