What repairs can be expected with a low flood damaged 01 Disco 2 (not running)? Mechanical? Difficulty level?

 

Man! It's so hard to say. Is this a truck you already own? Or something you're looking to possibly buy?
If you're going to look at it, I would check all fluids and pay close attention to any wiring at and below the high water mark.
Any idea how long it was submerged, or partially submerged?
