Jeep has just invested heaps in warehousing of spares in Melbourne, part of the divorce with DaimlerChrysler. Chrysler's new head office is now down Port Melbourne way along with their new warehouse. Previously we had to wait for parts from Singapore.. Fiat has changed their business model.
With the huge sales volumes of the new Grand, they can't keep up with demand. Even still they are struggling to build JK wranglers as it is. Demand is that good.
I don't think they are going anywhere in a hurry.
