Richard, and anyone else interested...
I imported this car myself and sold it to Ahmed. I can certainly vouch for the quality of it. (as still seen in my profile pic)
This car has/had a few Nismo options that seem to have been installed when near new, including the dash cluster. Overall condition of the car also leads me to believe this.
I believe the Japanese log books are with the car, along with receipts for everything that has been done in Australia.
When I sold the car I provided copies of the Import approval, Japanese de-reg cert (which states km's) as well as a few other items to Ahmed.
If you have any other questions feel free to also contact me, as I can also translate any Japanese documents that are still with the car.
My number is 0403 271 517.
Cheers,
Beau
