Just to clarify the pre-06 cars had coloured relectors in the front bumper (smaller IIRC), Brembos and 18" alloys (Rays were an option but still 18"). The three slat grille is probably the easiest way to tell an 06 without showing you comparison pics of the inside but, of course, there will be the odd older car that's had a new style bumper retro-fitted. Post a link if you find one and we can clarify.
