They do share the same ecu as the new model commodores and as such can be adapted to flex fuel. Given they are the same ecu also means that pretty where anywhere in Australia will be able to tune them.
Personally if the looks don't get you into the Astra the seats are what would seal it for me. The Astra is just such a nice place to sit and enjoy the drive and in terms of performance and fun the front diff is confidence inspiring and from what I have driven in one does have an awd feel.
The wrx is a nice car but the issue with it for me is they are everywhere. In Adelaide at least. The Astra is different and turns heads
