No one really knows how Tesla VIN’s work. I would go in with an open mind take your time and inspect the hell out of it. Document any issues with your delivery person, take pics, If it’s acceptable to you then take delivery. Set up a service appointment to address whatever issues you might need fixed. I would be curious to know what your SA means by “all the latest updates”. I’d want to make sure anything you’re wanting and expecting us there. Congrats and good luck.
