Given that So Cal is one of BMW's largest markets (if not THE largest), they left themselves without any new model introduction at the L.A. show. The 6-series was shown last year, and they have been on the streets for a while, so that isn't new. The i models are just concepts. The 911 and 3-series both debuted at Frankfurt; the 911 was at L.A., and BMW started marketing the 3-series to North America on-line over a month ago. To me, the L.A. show seemed like exactly the right place at the right time for a US introduction.
