Here is a live example of the shipping timescales:

So the cars will be loaded at Charleston, and it takes approx 22 days to ship to the UK, depending on when and where it stops. Once you get your VIN you will be able to search using the linked website.

They seem to load them on the boat to Germany/UK every 7-10 days so Production time (1 week) + Lucky dip on the boat (say worst case 10 days if you just 'miss the boat') + 3 weeks shipping to the UK + 1 week to transport to the dealer + 2 days PDI. So it could range from 37 to 47 days from starting production to being sat on your drive.

My production date was 14/12/13 (not sure if this is the start or complete date), loaded on 17/12, arrived UK today. At least that's what I think happened. It's possible it's only just being loaded onto this boat, in which case I won't get it until early Feb:
