My timeline is almost identical to yours:
Production complete: 12/6
At the port: 12/11 (confirmed by the dealer today)
The only difference: my vehicle is going to Southern California and I wonder if the destination may play a role in the vessel assignment. Some vessels go directly to the US-West Coast. Could my vehicle be waiting until this vessel becomes available?
For those on the US-West Coast with SA built vehicles, which vessel did your vehicle has been eventually assigned? Did it go directly to the West Coast? Or - did it make a stop on the US-East Coast?
