From BMW Group PressClub USA:

MINI USA reported sales of 4,326 automobiles, a decrease of 11.2 percent from the 4,872 cars sold last year.  The drop in sales was affected by the Cash for Clunkers program that took place in July and August of 2009 and boosted sales volume.  Excluding this one-off, the brand’s sales performance would have been ahead of last July.  Year-to-date, MINI USA also reported sales of 25,279 automobiles, a slight decrease of 1.9 percent and nearly on par with the 25,757 units sold last year.  In a segment that is down double digits year-to-date, the brand continued to gain market share.
