sounds pretty nice.. but i still think its sad that they had to use another company's work to get a car like that - they couldn't do it themselves, even if they had all the designs already drawn up for them..
i'm guessing the suspension is most likely carried over from the monaro, or tweaked slightly for the new engine. either way, it should be the same setup. the chassis dynamics are obviously going to come from the austrailain design.
interior? is that carried over as well? do you know if the transmission/clutch are GM parts, or are they holden components?
