I could be, just my own experience. From the outside, there was never really a facelift of the ISF, just the 2011 onwards got different lights, 2010 onwards got different wheel options.
Should your ISF have been an original UK supplied car with the black stereo surround, then iirc they left the factory mid-late 08 - mid-late 09, think the crossover month was September.
I imported mine from Japan, so the point I was making is that for imports, the UK number plate goes by the date it left the factory. UK dealer cars are different.
