Welcome to Perth-WRX!
I came from a 96 Camry CSI to a MY08 and later on a MY11, I can tell that you will enjoy the car.
Give it some time to get used to the dynamics and then have a look at improving what the stock car can offer.
Will be plenty of knowledge in this place that will be of use, should be able to find it using the search function quite easily.
Craig, if I had gotten a MY09 instead of the MY08 I most likely would still have it
