I was only told it was one of the first 6 but have not been able to find out more. I got very excited when I learned that my VIN was 100301 thinking that it would be number 1 of 200 but I think someone posted their VIN lower than mine. I hope they don't do what they did with the Final Edition GTS - draw dash plaques at random from a box with no regard for build order. That was lame.
My bet is that they will do exactly that. It was what they did with the VCA Edition cars as well, which were supposed to have been the first 2005's built (they weren't). The numbers, at least for the VCA cars, were put in when the completed car was ready to go to the shipping room. So, if your car had, say, a slightly misaligned hood, it would go back to the department that fixes stuff like that (and I should remember the name but don't). Meanwhile, all the cars built after yours are getting a lower number as they go to the shipping room because they didn't have any fixes required. The VIN had absolutely nothing to do with it. For example, with the VCA Edition cars the #020 car has a VIN ending in 500426 - the highest VIN on these cars. The #047 car has a VIN ending in 500037 - the lowest VIN.
Bottom line: Don't count on any particular number.
