thanks all brothers
I am in contact with the guy from whom I am going to purchase the vehicle, once he responds to my query then next step will be to re-route my flight from Dubai to Karachi ..... as on 22nd june I am already booked for DXB-ISB flight, so instead I will make a stayover in Karachi, test and check the vehicle, do necessary documentations and then will hand it over to carrier guys while I fly to ISB.
Nasir sb from Family Movers International (searched him thru web) gave me a quote for Rs. 18,500 to deliver the vehicle from KHI to ISB. They need NOC and Registration Book.
Lets hope all goes good and I get what I want, Insha'Allah
Keep feeding me with your experiences and information regarding this.
