Call me whatever but I always liked the Explorer more than the Fortuner.
I agree with navadv on the resale part.
A Rav4 is a better buy than the Pajero if you won't be going off-roading frequently and don't have more than 5 people to haul around. (the Rav4 is more spacious than MOST SUVs in the back, including the Pajero) You'll also save fuel and get the solid Toyota reliability and ownership experience. The Rav4, being a 'city SUV' is more easier to haul around the city and park compared to the Pajero and you still get the commanding view and safe feel. The Rav4, being more adapted to the city, is even safer thanks to better roll-over angles compared to the Pajero.
I am not exactly saying that the Rav4 is better than the Pajero, but I am just suggesting that you buy something that fulfills your requirements better. Both of the SUVs are good and have their own strong points.
Just ask yourself three questions:
Do I need 7 seats?
Will I be going off-road very frequently and in tough terrains?
Am I ready to pay for the fuel consumption of a V6?
If your answer to all of them is 'NO', then buy a Rav4. If it is 'YES', then go for the Pajero.
I still would recommend going for something that your heart feels content with.
