Each OEM, including Tesla, maintain a database where each ever produced vehicles with all the options, including changes are recorded. Except, when they screw it up. They screw this up with PR samples and show cars, which are sometimes prepared by hand and finished up by hand just for the press or just for show. Then things get forgotten to record. Tesla had so such problems. Volkswagen had such problems and had to recall a 5 figure number, just because of this. Because PR and show cars are normally discarded after the show, after the press had it, but sometimes they get into the second hand market.
