yes it is.
Some do, some don't. Our cars are 100% Australian anyways.When you do a rebadge do you change the front fascia and hood as well? I am not sure I understand the concept if you don't. What would be the point in a car that is half Pontiac and half Holden in appearance? Just one of my odd thoughts.
The few "limited edition" commodores I've seen have no front badge, so I'm guessing they don't make a Holden badge that fits our front end.
