Why is the Yaris with factory alloys so rare?

[eht13]

I meant to add that maybe this has changed... maybe the OEM alloys are more often tied to the "Sport Package" that is available now. In the past, before the Sport Package, it was either the S or not, and the OEM alloys could be just as easily upgraded to either way (like in my case... non-S sedan with OEM alloys).

The chart below (from the Toyota site) indicates that the OEM alloys are still an option regardless of package, but maybe that is not how the cars are usually sold in reality anymore.

The pic below that (again) from the main site shows a 5-door HB that does not have the Sport Package, but does have the 8-spoke OEM alloys. But again, maybe not often seen available in the real world.
