It happens. You probably got a car that fell through with another customer. It does not necessarily mean that it fell through because of a problem with the car. It could have been a customer financing issue for example.
In my case I ordered on 8/4, had a vin less than 8 hours later, and the original delivery date was 8/8. I was truly worried it was a reject due to a problem. First, find out the build date for your VIN. Tesla can tell you that. If it is recent then no worries. Mine was built June 3rd so I asked the reason for the delay in shipping. They told me it was a customer that did not respond in time so they released it. That made sense and may have actually been partially true. I found out after delivery that my car has been completely repainted and that was probably the reason for the delay. I see that as a bonus since my paint is twice as thick as normal Tesla paint. Sometimes the delays mean they are just making things right. My point is keep your eyes open for the real reason that your car might have been delayed originally (if it even was at all) and report any issues as soon as you spot them.
My last MS was a 2021 LR+ and I drove it wishing almost daily that I had bought the Performance model. I did not make that mistake this time. I hope you enjoy yours.
