The first 100 cars are assembly line built production cars, not pre-production. They are being super QC'd so they get pulled off of the assembly randomly. The cars being shown the last week on the IG and FB pages, are actual customers cars, that are in the "accessory" stage, meaning, they are 90% complete and having their individual accessories added.
When I received my call from Robby about being moved from #125 to within the first 100 cars, he specifically told me that, his "friends" were being moved out so that customers would get cars before them, and that California dealers, specifically Coyne, would not be getting cars until they go their CARB cert. So no, these first 100 are not elite friends, or test mules.
