I know that there hasn't been anything official yet and everyone wants to know what # of production their Shelby is and while I was looking at My Ford Credit acct it gives a breakdown of the VIN#. It states digits 12-17 is the production #. Mine was built in the first quarter and is a numer in the 2000's with the last 2 digits possibly being the year-07. Does this logic work on anyone elses VIN#. 12-15 being you # ?
