It would be interesting to see sales volume by year. For example, the entire economy melted down in Q4 2008 and car sales in the US, in 2009, fell off a cliff, especially expensive car sales. 2010 was not much better. Maybe in 2009 BMW only sold a fraction of the cars they sold in 2008 and 2011.
Does anyone know if this data is available?
