Discovery or LC90

[banano]

Hello all!
Im going to change my old Hilux to something newer that will be good enough for some trips to marocco(or mayby egain to mauritania?who knows?)
And Im pretty not decided what to chose.
I see two possibilities good for me. LR Discovery 300Tdi (till 1998) or Land Cruiser 3.0 D4D(mayby KZTE, but I better like D4D due to lower fuel consumption)
As all we know Discoverys from 1998 are almost half the price of Land Cruiser from 2000-2001.
So If I chose Discovery, I want to install Maxi Drive locking diffs(four pinion diferentials,strenghtend drive shafts ect..) in front and rear. (I heard that LR orginal diferentials are not great) and all new Equipe4x4 suspension in it, plus some other changes.
All that Disco with extras will cost me probably same as 2000-2001 Land Cruiser J9
One more thing, when I buy Discovery 1998 i get something around 130.000-160.000km on the clock and in 2000 LC i have around 70.000-120.000km.
And here is a question. what is better? what should I chose?
for me the most important thing is reliability and fuel consumption.
space inside is not so important.
Please help.
