That's standard Toyota practice (and other importers as well): one of the reasons people buy the grey import cars from Japan is that you get a higher spec for less money. Classic example is that apparently the Tarago sold in Australia was de-specced by Toyota Australia to save money, but wherever it wasn't obvious, like swapping in a cheaper rear suspension. It looked the same as the Estima and Lucida (the Japanese market versions) but it didn't have the same mechanical specification. And you couldn't get the 4WD versions at all.
Yep, rusted on buyers.
