[Crazy Dazz]

I worked in Indonesia and Viet Nam.
Not sure why, but even back in the day when it was a re-badged Mazda, the Ford Ranger was extremely popular. It just seemed to represent very good value for money in the light-truck segment.
(Oh, and Indonesia is also RHD.)
I've never been able to confirm, but they MUST have been assembled within Indonesia (to avoid the crippling import duties.) Perhaps they came in CKD?
Again Ford has an assembly plant in Viet Nam for the same reason.

My point is that the Ranger is popular throughout SE Asia in a way GM products never were. Don't know whey, just the way it was.

So as long as the Ranger remains popular, and Australia remains the design centre for the Ranger, I guess their jobs will remain.

Something else to keep in mind, is that Ford is still family controlled.
So whilst companies like GM will cut off their own penis if it isn't profitable, Ford will always be a little bit more reluctant to abandon a market.
Same reason why Ford has always preferred to put their own name on cars.
