So last week we declined our Y (VIN 14804) due to the issues we saw at delivery. Yesterday I got assigned a new VIN (219XX) but no estimated delivery date, but seeing how people are taking delivery of VINs in the 23xxx range and above, my first thought was whether I am being assigned a car built a week or two ago, or one possibly rejected by someone else. I called Tesla to inquire. They basically said this VIN is still in pre-production, meaning it hasn't started being built yet. When I asked about VIN ranges, he said they're not exactly random, but they also don't follow a sequence necessarily. so this VIN has been assigned to a vehicle with my specs that's lower than many of the current VINs being delivered, but just hasn't been built yet. So hopefully this provides some clarity...or further confusion...on VIN assignments.
