This doesn't apply, as Holden sources these cars from other GM brands, it doesn't desgin and build them itself like Nissan Japan did with the Skyline. Holden decided to switch from the European "Opel Corsa", to the cheaper Korean "Daewoo Kalos", while keeping the Barina name. Nissan obviously didn't do this.
Maybe, but it doesn't relate to this argument though does it? So its not relevant.
