Nissan Patrol 4x4 (Africa)

I'm trying to do a cost of ownership calc. Does anyone have an idea of costs from about 60000km to 200 000km? Life expectancy of brake pads / discs and cost. My pathfinder ate pads for breakfast.

If I recall the 90 is a big one? Basically the scheduled items and main wear and tear items.

I am changing pads for the fist time at 140 000 and the platinum plugs at around 100000 were a bit steep also the transmission oil at 120 000 otherwise oil and filters
