We have a 2008 turbo diesel automatic Pajero and we love it. It rides very smoothly and is really comfortable on long trips. It has heaps of room, especially in the 'boot' as the back row of seats stores under the floor. I've had our 50L car fridge, two prams, two suitcases, nappy bag, a carrier plus bedding in the boot. The only downfall was when DS was rearward facing I couldn't reach him without physically moving my seat back or getting out of my seat belt and turning right around as the back seat is quite roomy too.
When we were looking at a new car DH researched and found that in our case, what we wanted on the Pajero was about $10 000 cheaper than the same on a Prado. So we found the Pajero value for money, also has a great warranty.
Just asked DH and he said that if you're constantly driving on rough roads you should upgrade the factory suspension on any 4 wheel drive, the aftermarket suspension is specially designed for Australian standards. If you want his opinion on brands, just PM me. And that the new model has a 3 ton towing capacity.
Hope that helps!
