being in the UK/europe, if i were you,id go for the twin turbocharged straight 6(aristo) instead of the v8 (even more power) and there are specialists in the uk hat will convert the touch screen so the sat-navigation will work (if it hasnt been converted already)
both cars do however have the electric brake booster,so be wary of odd squeaks and a pump that is constantly purging ...and formorepower,get any imposrt specialist to tune it for you, or get a reprogrammed ecu from japan (there are loads of options, i got myself a blitz access ecu for my mK1)
