Some of them came with an Isuzu engine,a much better engine,they are OK off road if all the junk is removed,like running boards etc.
You might struggle getting parts for the Frontera more abroad than parts for a Disco or other Landy.
It might be cheap for a reason,be carefull you don`t buy someone elses mistake,check well for rot,any odd vibrations or anything that could be costly to repair.
Good luck
