2k1toaster - Hybrids eh. From now on we'll call you captain planet. They're still too expensive over here for them to be anywhere near mainstream.
Raf - The commodore is the standard 6 cylinder Holden family car. They move up into v8's with the SS (Pontiac G8) and then up again into the Monaro's (Pontiac GTO's). Then there's HSV (Holden Special Vehicles) which make the 327kw versions of the Monaro etc.
The standard commodores ar rear-wheel drive. You can get an all-wheel drive wagon version of a commodore called an Adventra. They are available in v6 or v8 configs.
