Thanks for that Tony.
A bit about myself, well you wouldn't believe it but (you might) i have always owned LANDROVERS.
Now don't turn off your computer because i am just about to buy a 07-08 cab chassis 3.0Ltr CRD Nissan.
Why, because Landrover stopped making cab chassis in 1998 when they made the TD5. Shame.
Not keen on going back to free wheeling hubs, constant 4 wheel drive (cental diff) is the go. Never had any issues with Landrovers, i've had seven and built a Discovery. There are lemons amongst all makes.
Hope to have as good a reliability record from Nissan as i did from Landrover. Sometimes it's the owner and how they drive and maintain machinery.
