On my import Insurance difference is about £80. Tax is £280 a year. Battery posts are different and battery is smaller. Lots of labels in Japanese. No clock, indicator stalk is on the right hand side and the wipers are on the left (quite annoying if you drive different vehicles). However mine has a few nice unique mods on it like a kakimoto exhaust, prodrive alloys and underseat lights. All in all I'd say don't let it being an import put you off, I looked at plenty of uk cars that weren't in as good as condition as mine.
