The news was that the govt. was going to decrese the import duty on imported cars,but the japanese govt. interfered.The japanese ambassador gave a statement that japanese companies have huge investment in pakistan and they will suffer heavy loss by decreasing import duty.So the matter was postponed.
It was decided that the matter will be discussed 3 months later,during the time VAT will also be imposed,and things will be more clear.
So you have to wait at least 3 months,if you want some variety at reasonable rates.But who knows that import duty is decreased or increased.
