There is a number of articles appearing in magazines and papers about the 300C and some critiques are good, some very bad.
Wheels did a comparison with a Caprice, Fairmont Ghia and 300C HEMI. This is the most favourable article I have read however they did not rate the 300C highest.
Last Monday night on SBS was the Top Gear show comparing the Jag S Type R, Monaro (HSV spec'ed) and 300C. This has been around for some time but reopened an old wound for me as they had a fair swipe at the 300C.

"Not much torque", are they kidding??
Unique Cars write up was a terrible evaluation. They were critical of the quality of interior plastic & fit (Wheels reckoned plastic was high quality), said the switches were cheap and the cruise control nasty and hard to use (have these guys ever driven a Mercedes?? the switches and stalks are exactly the same and are they considered cheap?) and the handling disappointing but satisfactory for "mum & dad drivers with kids on board".
The Melbourne HeraldSun was an okay roadtest today, speaking highly of the 300C HEMI but then closing by saying not as good as the local product and rated 14/20. Bloody amazing.
Interested in others comments.
