Well,
Per findings in the 'How Many Model' thread, it seems, due to different registration methods across the globe as outlined by members on both sides of the pond, that the only way to properly catagorize SVXes for year/date/registration is per Subaru Applied Model code, A,B,C,D,E,F, which seems to be consistant with every Applied Model except Dan's GCC code of T. T may mean some type of exception or variation from standard, or perhaps that region has no model requirements. Still, for purposes of the lowest mileage single SVX, it is what it is.
As for UK AMs, per Joe's Trim Registration thread, there are codes A and B for UK SVX, CXWAK7E, CXWBK7E, so, these are not the same model, unless there is a typo. It appears that this is not a 'A' being sold for multiple years
