When I was waiting for my 2019 LR AWD (built on October 4th) asked my OA if the 2020 cars have any hardware changes compared to my 2019 since I could just switch my order to a 2020 car to be delivered in December. He said Tesla corporate confirmed that 2020 cars are identical to 2019 and the only reason Tesla had to switch to 2020 VINs was to comply with some local laws in market overseas. This makes me nervous in a different way so the 2020 cars are not identical to late 2019 cars then. I wonder what else might have changed (for better or worse)...
