Was in there today, looks dramtic enough but not sure I could live with the whole white / stripe thing.
As I understand it, its mainly the suspension you are paying for on the standard Bathurst. Other bits are nice but not significant. Even has the standard exhaust.
Just buy a nice LS3 IMO. Small cam with retained emissions compliance and Id almost put money on 400rwhp. All nice and as standard. I doubt you would even need to replace the exhaust.
I saw one at goodwood fos on Friday. It makes a great sound driving, deep exhaust note with a distinct whine. Looks great cornering at high speed as well, sticks to the road like it's on rails.
I saw the Bathurst at Goodwood yesterday too. The whine of the SC up the hill was fantastic. Still not sure it's worth the £50k it cost with the extras compared to a boggo VXR8 but it looked and sounded great
