I think this is the one! Basically you have have the 276BHP model which goes up to 06 plates, the 296BHP facelift model which runs to 07 plates and then the 313BHP engine bulge which is anything after.
There are a few differences in these models from engine to light types and wheels etc. Also depends if the car is a Gt which gives it heated electric seats, BOSE sounds etc. And these is JDM models (usual giveaway is non brembo or square reg plates but not always)
Any specific questions or if you have an advert post it up and we will look and try and help you out.
