Pretty hard to tell what it is, without a VIN. I would concur that Mr. Shirley's car (which is Blue - a White car was representing it at the Christie's Auction in Monterey where he made the deal for the rights to buy the "first" production car) was the first Retail delivery, though in the database, his vehicle shows up as a "Dealer Stock" order.
I contacted Legendary, and got the VIN of the car (5-0046). It IS shown in my database as the "First Retail Order" - the car was built 8/13/2004. Mr. Shirley's car (5-0010), which is the "first car delivered to the public" was built 7/23/2004.
The last 2005, which has the highest 2005 VIN, and actually WAS the last 2005 model built, is 5-2068. According to my data, there were 2027 '05 model Ford GTs built. I have not been able to reconcile the count difference with the data from the SVT package. I do see five units in my data with a unique code that I have not been able to decipher - I would guess the SVT data is not counting those units for some unknown reason.
