Introduced here (in museums) here earlier this year, Smart USA began taking orders on the Internet .... on a design-your-own, reservation basis. A dealer network has now been put in place as well.
I spotted two Smart ForTwo's in the past 2 days. (They're VERY small .. but very cool).
One was here in Central PA last week, and another on a brief biz trip to New York this past weekend.

You can find out more of the Mercedes Smart ForTwo at the SMART USA website here.
