I was at my dealer today and he had talked with the planner here in Germany
US Spec Cars Build dates"
"Production will start 12/07 but these slots will be used for launch events, media information etc. We will have production before 04/08 but not by much. There will also be a 4 door version but He would not give us the production dates"
He has been very accurate in the past so I would expect a Spring launch in the US. I am really interested to find out what if anything they do to freshen the Sedan, Maybe the M will lead that.
