Kinda feel for the yanks, they get sloppy fourths. First NZ had the pick of the bunch, then AU under RAWS and SEVS, then 15 year rule, then Canada got a whole heap of them under their 15 year rule... so now the stuff that's left in Japan is either top notch examples owned by collectors that command top dollar, or nasty ones that the rest of the world doesn't want.
Getting a GTR out of AU might be better in some cases than out of JP. Lots of Porsche owners are starting to buy cars from AU instead of EU cos of the condition that the cars are used in. Plus we have tighter regulations on repairs and roadworthiness than in JP.
