I have taken my landcruiser to pakistan quite recently. It was 2998 cc toyota landcruiser LC4 D-4WD, manual. It was first registered in Uk on 8th september 2004.
Tax, duties + bribe is almost 2.8-2.9 million rupees. I have taken it to pakistan under personal baggage scheme, it is still sitting at islamad dry port. Customs need my original passport to get it cleared but since I am in Uk and busy with some other stuff, it is still there. Hope I will get it cleared sometime first week of march.
If you guys want to bring cars to pakistan, DONOT bring at islamabad, get it cleared at karachi. In karachi lots of vehicles get cleared every day, you spend less money bribing customs and less hassle.
