You're right my bad, 50% depreciation on value assessed, 90% of which will be custom duty. So it's a total of 25 Lac extra (including taxes) to bring it here.
Edit:
Here's a quick method to do it:
The vehicle is not Japanese so it's under normal regime. It's over 1800cc so customs duty is 90% of value assessed (after depreciation). Value assessed, for all practical purposes is the cost of getting the vehicle to a port in Pakistan before customs and taxes.
Next: Depreciation is on value assessed at 2% per month since the date of first registration abroad, capped at 50% (might be 60% now, no legal documents have been updated since 2008).
Sales tax is 15 of depreciated customs duty + value assessed.
Income tax is 5% of Sales tax + depreciated customs duty + Value assessed.
FED is 1% of depreciated customs duty + value assessed.
As long as you can find out the assessed value, you can do the maths for all other costs by yourself.
