+1 wot Ferrit said. Watch out for the pulley bearings for the pumps/air conditioning unit. They are weak and will go at about 60k miles so make sure you're warranty will cover that or just get the importer to change it before it goes. The engine will run on and you can do damage to engine casings :o(
I put bigger wheels off a HiLux on mine (minor body work alterations with a lump hammer) and the difference off road for grip and clearance is impressive, another vote for going 29er (not so easy to manual tho ;o) )
I have the 8 seatet which gives me about 29mpg on a run but down to 10 towing excavators. It used as a family runabout, uplift bus, camper, truck for delivering bikes, race vehicle, trail digging tool, I used it to tow mini diggers out of holes they're awesome trucks and can be driven pretty much like a car definetely a quieter and more luxurious ride than your average 4wd pick up and landy.
