contact Sharabhi on this forum, he is good guy for self import!
if you want to do all by yourself its also possible register with a car auction house agent in Japan first, then you can bid for cars you are interested. They will charge you fee for registration , if won, They will charge you shipping to port and then to Khi! in Pakistan you hire agent and release the car!
on the same note, if you importing one off car, it may prove costly to pay overhead like auction agent registration fee and shipping cost to Pakistan as bulk importer get cheaper shipping rates plus they ship more cars per container and you dont have to be registered at japan auction agent.
both ways you get the car you really see on auction sheet and not fake or tweaked, thats the real edge comparing with buying from local car dealers!
