My first skyline i imported through adam @ feast. Took 6-7 months to recieve the procedure was easy and at the time wasnt too costly. If i were you i would recommend picking up the car locally say through rightdrive or a independant seller, this way you get to see the car up close and personal.
If your looking to import Shoot adam an e-mail. I believe its Info@feastautoexport.com He can find any car you really want. Unfortunitly me and him had a falling out of some bs but i still think hes one of the best to source cars.
