Sorry for my distrust, but I can't approve some of the good information Jussi gave.
1. If Scott says there won't be a M3 in US till Spring 08 this means guess what: There won't be till spring 08. Supporting that delayed introduction for the states is the fact that there is not one single m3 prototype seen in the US which is from the FEP stage. All the cars cruising around in America are early prototypes. So my guess stays: The time frame Scott gave is quite accurate.
2. There are strong indications that there won't be SMG at all for the M3. The M3 starts with a manual (enough for me) and there will be a DSG, but it's delayed till at least spring 08 (which could be another reason to wait with US introduction).
3. There can't be a "production" car in May because the production will not have started by that time.
Best regards, south
