After posting the Middle eastern Chevrolet Caprice, i scooped around on the GM site and came at the Australian section.

Now I'm really confused,

The middle eastern Caprice is the same as the German Opel Omega, the UK Vauxhall Omega, the American Cadillac Catera. But that makes sense because you market the same car under a different name in different countries.
But when it comes to Australia, you guys have got;
-Holden Caprice
-Holden Statesman
-Holden Commodore SS-Z (and many other version of the same commodore)

Why , in principle those are the same cars. Only the commodore has a slightly different nose/face.

Probably its a success because all three cars have just being updated, and they still look pretty much alike.

Question : What's the difference between these three cars, why would i (if I'd live down under) buy a Caprice instead of a Statesman or Commodore ?
