Found this when looking at wheels on Gumtree. It seems Toyota Australia in 2008/09 approached Auto Salon to upgrade a Yaris and a Rav 4 for a car show.
Almost a decade along the Yaris is up for sale. It appears to have also lost its original titanium wheels as well.
Here is some original info on it:
And you can find plenty of articles on it including posts from the head of the project on other Yaris forums by googling: toyota camouflage yaris project ng
It would be cool if it could get into the hands of those that would really look after it. Hopefully a forum member picks it up.
