I think it is because of the price and duty factor that most of 7-seats are 4x2 drive. Just like Juke, most of the Jukes imported in Pakistan were FWD you will hardly find and 4x4.
Not sure about your budget... but if you are thinking about Prado, I would suggest that you also look for Surf also..though luxury feature wise Prado is much better than a Surf but you will get a newer model
