personally i reckon importing wouldn't suit the "first import" buyer.. as you probably wouldn't know what to look for or what questions to ask. But I am sure plenty have gone this route.
Just look for a private sale if you ask me. Best way to do things. If you look on here sellers, there are plenty of advantages:
a) the person is unlikely to rip you off, especially if they have been a regular member and post regularly on here.
B) you can email them questions and request photos before even looking at the car. Saves both of you wasting each others time beforehand.
c) you know they love skylines as much as you do, and have probably taken care of the car.
d) you might be able to find some of the past history of the car and any problems they might have had with it.
