i work for holden and have for a while, i have driven basically all of them including most of the VE HSV range, for what it's worth i really dont rate them. Handling is nothing like a jap car and they are really not fuel efficent. i used to have a twin turbo supra and i have been in alot of GTR's and you cant beat these as a complete package. handle well are quick and better on fuel. It just depends what you want but i suggest you take them for a test drive before you make your decision, then you will know what i mean.
The clubsport is good in a straight line torquey down low but just not exciting to drive.
