For £6k your looking at an Import Auto. UK spec insurance is usually cheaper than imports. UK specs have different turbos. Apparently they don't spool as quickly, but give a bit more top end for the European Autobahn cruising. Both give the same power (280 is a myth due to the 'gentleman's agreement' they had in Japan)
The auto is very good and responsive, not like the usual auto rubbish I'd driven before I bought mine. I absolutely love it. Easy to drive in traffic and gives super fast gear changes every time up to the red line. Also has a manual mode selector for more spirited driving, although TBH, I usually just knock it between 2nd and 3rd on a fast run.
