Yeah Turbos were a bit out of the price range I wanted to go to - I also prefer the NA drive though, less likely to toss you off the road at a roundabout etc!
I did go out in a stage 4 VXT, about 360bhp I think it was (so putting it at about 500bhp per tonne), christ almighty that was quick, far too quick for my meagre driving skills. Like you say though it can corner like you wouldnt believe and is a far more involving drive than any other car I have owned.
