That sticker is not what the original buyer bought. What they bought was laid out in their sales agreement. This sticker shows what the options are, because the hardware exists in the car. It is not a bill of sale. It is a disclosure of hardware in the car. That is literally it.
The dealer who bought the car did not read or ask for the original sales agreement, and instead assumed that every option had been paid for. That is completely the dealer’s fault. When buying a car, you do your due diligence; check carfax, inspect it for mechanical and cosmetic issues, and so on. One of those things is also ensuring it isn’t stolen, has a free and clear title, and has the feature you think it does *and that they work.*
That is all the dealer’s job. They failed to do that here, and then sold the car after advertising it as having features it didn’t, due to a mistake they made.
I’m not sure how to make that any clearer.
