This actually seems like a really good fit. As I understand it, the Scion line is targeted at young people who want to customize their cars in a modular way, so they look unique. That's probably the same kind of people who would install custom themes on their iPhone. Plus, it's surely cheaper than iAds, they're making news, and it's probably good for that edgy image that they're trying to obtain.
