Welcome to the Forum mbrooks. :wavey:
The VIN is the first step and the Ford reps can sometimes get a build date for you from that as should your dealer. The 'Window Sticker' usually is available for lookup 4 to 5 days before the actual build. The sticker has the build date on it in the lower right corner. From the build it goes out to the lot to await shipment and depending upon where you live will be shipped by transport or rail. The usual line from the dealer is 8 to 10 weeks from the time it is ordered but some 2013's have been arriving in as short as 4-5 weeks.
The problem at this time of year is that the factory shuts down for 2 weeks for the holidays.
I ordered my 2011 just before Christmas 2010 and it arrived at the dealer March 11th, 2011.
Good luck.
