Slightly off topic but maybe relevant to the Randomised Vin build topic - I get the Australia push notifications as well as the UK ones, and one advantage of them over looking at Teslas website is you can see the build date. I've noticed Australia had a "2022 M3P" built on 16 Oct, whereas the UK have a "2023 M3 RWD" built on 8th Oct, both built in the same factory. The spec differences are the Aus car has USS and the UK doesn't. So we have 2022 spec cars being built after 2023 spec cars, so the year appears to be linked to a kind of model year, and not all 2023 cars are built after 2022 cars, If that was what we thought was dictating order of build then it doesn't seem to hold true. The same website has a vin / build date graph and it's pretty consistent since 2020 with cars being built in VIN order, or at least it's nothing like it used to be back in the early freemont days. There is the odd outlier, but not many. That said, the data is more scarce in recent months as I presume it takes times for VINs to get picked up. There;s a similar pattern for the MY.
If we want to discuss this further then I'm happy to break it out into it's own thread, but I wonder if the year in the VIN has confused people regarding when cars were built,. when its more a reflection of spec and whether the car has USS.
