Today, I received in the mail, my deluxe build sheet on my 2011 Shelby GT500. Some pretty cool information on it, it breaks down the entire VIN, which was nice but also gives the dates when the Shelby was first ordered, a scheduled build date, the actual production date, date when released from production, and the actual sale date. 
It goes even further in depth with Production figures.
2011 Shelby GT500 figures
5,100 Shelby GT500 Produced
950 Shelby GT500 Convertibles
102 Shelby GT500 Convertibles in High Performance White
1 of 14 produced with this vehicle configuration.
Also received my GT500 Owner's Certificate of Authenticity which states build #688 out of 950 convertibles and build #70 out of 102 manufactured in Performance White and also have the VIN and build date.
Still waiting on my Shelby Certificate to arrive.

Also happen to be the only 2013 vert in my state (not too surprising...not too many fools up here will buy a convertible with the short, cool summers).
