Well your analogy will not work because every other car is expensive in Pakistan due to high % of taxes.
If I use your concept of calculation, The Australian customer should pay 56,000 Australian dollars for Santa FE hybrid BUT the hybrid cost is around 68000 to 70,000 Australian dollars.
A British customer should pay around 30000 British pounds BUT the average cost of Santa FE Hybrid is around 45000 GBP.
