I can see by the Registry page (www.dodgechallengerregistry.com) That the Vin's are starting to mean something. When you sort by vin, the lower the number the more that are in d-1 or higher. A few (3) show D1 in the 30---- range, but perhaps they are not updated. Remember when the vin vs build dates looked wrong?
The bad news is I am in the last of the VIN's even though it was ordered on 12/3.... 300590
