Just wait for the all-new Fortuner, considering the Fortuner is already 4 years old. Although I never had a Fortuner, I doubt the 9 - 10 kilometer fuel efficiency of the 3.0 D-4D. But anyways, I suggest you go for a gas Fortuner, in my opinion, gas is definitely better than diesel, although diesel is cheaper than gas, but consider these : no noise, no vibration, no carbon black emission, faster acceleration, diesel engines are more expensive to maintain, they usually have 2 each of fuel & oil filters, bigger (expensive) air cleaners & oil changes.
