For those curious, here are the full numbers for the BMW Group in North America:

BMW of North America, LLC reported a 10 percent decrease in April sales of automobiles and Sports Activity Vehicles, to 21,072 vehicles compared to the 23,419 reported last April. This decrease was due primarily to the successful build-out of the 2005 3 Series sedans, in preparation for the launch of its successor, resulting in lower inventory of these high volume models. The all-new 2006 3 Series sedans will go on sale this Friday, May 6th. ??>Year-to-date, sales of BMW brand vehicles were slightly higher than last year, for sales of 76,424 vehicles compared to 76,389 vehicles sold in first four months of 2004.
