Swift is a good car but it's not a Japanese import. The car is made by Paksuzki and localization is increasing every year. It's true that 2010 Swifts had a lot of imported components but that has changed with time. Now more and more parts are locally made - you can confirm this from any dealership service. Furthermore the next fourth generation Swift will be unveiled at the Tokyo Motor Show later this month, while the Pakistani model is a second generation swift. The fourth generation Swift release will make Pakistani market two generaitons behind.
V2 has significant price difference (and taxes as it falls in 1000-1300cc while Swift falls in 1300-1500cc tax catergory due to 1328cc engine....and the M13A engine offered in PKDM Swift lacks VVT which is available in JDM models). I have seen second generation Japanese Swift, there is a lot of difference from Pakistani model staring from Airbags, VVT Engine, rear wiper&washer, UV Cut glass, Force Limiters - pretensioner seat belts, Outside Temperature Sensor, Fuel Economy Meter, Option for climate control, luggage light, etc..... the jdm version also has protection frame inside the bumper..)
