Many here have told us their VIN. Question ... if you have Model S VIN 4500, and you have a 2013 car, does that mean VIN 4500 have been produced for 2013? Or does that include 2012's? Put another way, if I have (2013) 4500, is that the 4500's Model S to be built, period? Or 4500 just for year 2013?
