I saw one today as well, actually... a fairly rare site on our roads, but the Mazda dealership imports them and sells them... they had two on their lot a couple of weeks ago. I stopped to take a look - asking around $25k for them. I told the guy if the pricing was more in line with the Yaris than I would consider it... but for that kind of money one can buy a nicely equipped, well-performing car (coughSIcough).
I rather like the styling - not sure if I would buy one based on it, but it is interesting. I imagine the Scion offers decent value in the States, and I hear they're actually quite practical.
