There are several small operations here in the States and Canada importing Aussie spec Falc's. They are ore then willing to build you a repo of the "Hoon Car".
Just use a search eninge to find the subject, they are there. it costs about $US5K000 jto bring one over, have it inspected by the US Feds, and registered if you do it yourself. I bought my XC after it was over here so I saved on shipping.
And by the way, the XA, XB, and XC in OZ were built like the "throwaway" US cars of the era (Maverick, Fairmont, etc.). It's getting hard to find good ones in OZ and NZ.
