I've never doubted the toughness or reliability of a Hilux - hell no.
Unfortunately at the time a new model direct injection Hilux was too expensive and my old Hilux was a pig on diesel (15L/100km) and was that bloody rough it was dangerous.
The Navara was 90% of a Hilux off road but 200% better on road.
16 MPG seems a tad low even for a hilux - especially for the hilux diesel. But I am sure you weren't doin a lot of motorway work with it.
I was also considering bringing in a Tacoma since the taxes on large jeep and trucks is low here. Unfortunately, the fuel isn't cheap here. At the moment we are paying €1.58 per litre. So, that's roughly the equivalent of $8/gallon with the exchange rate taken into consideration. So it'd sting some since I can't get a diesel Tacoma in the States. Can you guys get diesel ones? I wonder if I can get a diesel tacoma on the continent...
Speaking of importing cars, a bud of mine is looking at importing a Shelby GT500 to Ireland. That is gonna be a mad car here.
