Welcome mate to the nuthouse.
I had a similar question and had them answered when I first joined... so erm... good luck...
Just kidding lol, depending what Jap version you get, and if you are not too bothered about resale value and higher insurance then I say get a Jap spec one. here are the difference in versions hope this helps
JDM Specs
Base---17" wheels, ABS,Brake assist,TCS,limited slip diff,xenon headlights
Version T---- leather seats, seven speaker bose
Version S-- 18" rims Brembo's and VDc(instead of TCS ? )but no leather
Version ST--leather +Version S spec
rear spoilers/sat nav and side airbags ordered as extras on all specs + loads of other Extras not seen on UK cars like auto fold mirrors ,different steering wheels, footwell illumination etc etc...
From the company you have mentioned Im not sure of, but there are plenty of companies outthere, pm Nixy and find out where she got hers as she got a good deal
