That's an interesting call, because the area Dapto is on would be worth 10million today, easy.
Getting a guard in mint condition isn't the issue, the issue would be getting it to WA in same condition. It could be insured but that just gets your money back, doesn't get the guard you need.
Wouldn't it be easier getting it through your local Nissan dealer? They could order it through the FAST system, ex Japan and you would be assured of it's condition when you picked it up?
