Glad to have you here highIQ.
There's been a few articles floating around the web suggesting that the iQ will be coming to the U.S. but they are nothing official. The article from this thread: https://www.iqcolony.com/forum/index.php?topic=39.0
stated that Toyota is studying the prospects for the iQ in the U.S. and a decision is some months away. "Some months" sounds like an awfully long time away.
