I realize this is speculation, and Tesla, so all bets are off, but with a typical manufacturer, there are say, 2022 models that can be delivered in August 2021, and 2021 models that can be delivered in August, 2021 - so in my mind it is the VIN versus the date that would count.
Teslas are a bit unique in that regard, in that they make incremental changes during the year, but I'd say the VIN controls all. Above I'm reading an N versus an M in the VIN which makes a lot of sense to me.
so the real question - if in 2023 you get one of the dusty 452s, is that a 2023 or a 2021 model? in my mind, it would be a 2021, delivered in 2023, and the warranty would start on date of delivery, but it would still be a 2021 based on build date/VIN.
I hope I get a 2022, and not a 2023, 2024, or 2025 at this rate...or even a 3022...
