Ok, if you want a real 4wd suv don't buy the Nissan X-Trail T31, the 4WD system works whenever it need to, not when you want it, the T30 X-Trail is the only one which can be going real $wd on demand, I used to have a T30 2.5L Petro 4x4 auto and used a lot of 4wd and it's awesome, the T31 just goes 4wd when it needs to, like ke70dave wrote up there, , I know this port is old, but at home i've got the T30, now I have the T31 and my dad has the T32, the best all around should be the T30, period.
