I have mentioned this b4 and i will again.
Holden seem to be the biggest car tease around, just look at the concepts that they have made, the Torana it was a hatch was a twin turbo and incredible styling.The ssx again another hatch, AWD, and again looked good (similar design elements to the ve sports models now that i look at it).
And obviously they will never bring the EFIJY to production but just look at that thing i know ppl who dont even like holden who would kill to get there hands on it.
My point is that when they bring out cars like this obviously ppl are going to start expecting or wondering when a production version will be coming out.
The fact that they have made turbo's and hatches at least shows us that they are thinking about it and they have made it so it wasnt just a "would'nt it be cool if we made a hatch" momment.
