Hallo Edward and a warm welcome in the Nissan Patrol Forum !
You already got a number of opinions ... and now you get one more.
I have seen the vehicle you were so desperately after and I think you should be glad that you did not get it.
I did not think that this specific vehicle was so well looked after.
If you buy a 4.8 in that price-range than expect to spend immediately another 40-50 k "to make it reliable" .
There is, next door (to the place which had your dream vehicle (GWM)) another 4.8. They say its a 2004 (but registered in 2005 / face lift , also white with I think it was 214.000 km for about 170.000 Rand. This car is slightly better (if still available). It is not as butch as the first one but in my point of view mechanically better. The biggest drawback is that the dealer did a h.A job in repainting the car.
However I would also personally go with Fanus`s suggestion and perhaps settle for a pre-face-lift 4.8.
those two vehicle offered look outstanding.
The other point is that the pre-face-lifts interior ages much better.
I would equally go with Dirks suggestion to consider the 4.5 as well ..... especially if it becomes your bush- vehicle.
If money does not matter too much than go ahead and buy the latest 4.8 you can afford.
If you are on a budget, I would rather go for a pre-face lift 4.8, or even a 4.5 and have a bit of money left to spend on the vehicle.
