Using the name of a local company was a master stroke by Gm. For 70 years Holden was able to sell it's cars as an "Australian Car for Australian Conditions", one that could take the punishment of the terrible Australian roads. Great marketing. Cultural cringe has played a big part in killing off Holden, Australians don't believe anything made in their country could be as good as something made in Europe or Japan.
People want what they cannot have. That said, there is a lot of imported late model F150's and Ram's on the roads here.
