The dealer purchased the car from Tesla at an auction according to Jalopnik, and as another commenter pointed out, the feature is documented on the Monroney sticker. It doesn't matter whether or not the first owner paid for the features or not. The car was re-purchased from Tesla (even though it was the dealer buying at an auction.) Tesla advertised that feature to the customer [the dealership], and it's value took the feature in to account.

Whether the original owner paid for the feature or not is irrelevant. The dealership paid for the feature, and it's on the Monroney sticker. Tesla can either honor the claims of the Monroney sticker, or face the consequences.
