Jason, yes Ford Motor Company
Holden is the Australian arm of GM. Very strong rivalries and loyalties but as Agua has stated, after nearly 100 years, the CEO's in the US have decided loyalty to Oz is no longer required.
Note: Your Pontiac GTOs a few years ago (early 2000s) were actually Holden Monaros which were built in Oz, converted to LHD and re-badged.
Also the pick up truck that is so popular in America is called a Ute in Oz (short for utility vehicle) It was an Aussie invention and wait for it, was thought up by a farmer's WIFE. She wrote to ford motor company asking if it was possible for them to come up with a vehicle suitable for taking stock to market during the week and take the family to church on Sundays. The first one If I recall rightly was based on a 1932 Ford Vicky (Victoria)
