Yes. You are absolutely right. My mistake, I did not add duties and other taxes correctly & properly, and also JPY to PKR conversion.
Here is some rough estimate and just as an example: ( @pwuser153942916697 )
Car price: 2,026,000 JPY (source: https://jp.center/st-2rHw5J5WnFTUWe.htm , auction grade: 6)
Transport charges from Japan till Karachi port: ~125,000 JPY (can be even more)
Total: 2,151,000 JPY = ~2,779,703.73 PKR (as of today, and online google rate. It does not include bank charges, conversion charges, and other miscellaneous / inter-bank charges, etc.)
Approx. Custom Duty: ~713,125 PKR (source: http://oliac.pk/autolog/getcustomduty.php with 1 USD = ~140 PKR, and till 31-12-2018)
Documentation charges: ~50,000-60,000 PKR (can be even more)
Total: ~3.54-3.55 million PKR (and can be even more)
(And this cost does not include freight charges from Karachi port to any where in Pakistan, and also Importer's commission. The final cost can be even much more than this figure).
I hope, it will give some idea. Please correct me, if I forgot anything. Thank you.
