Don't own one, but have pretty much driven every type of the newer Monaro's thats come of the line.
CV8's, CV8-R's, CV8-Z's, a few v6 models (!...) but the best ones are the HSV models. Got to drive a worked GTS a few weeks back, not sure on the actual output of it, but it was one of those 300kw models with a fair bit of work done to it.
In case your wondering how I have gotten to drive all these cars at 16, I work for Holden.
