Ill reply here as well,might be of some help to others too.
See when we have a car in stock and at our showroom,its duty is paid.
Now you cant do what you want,or you can but not like how you want it.
You can get a car from Japan after paying C and F but you wont be able to take the car out of the port till you pay the duty.
My advise get a car on lease.
