Could be both!
I've seen buyers load up the car with dealer add-ons, then buy the "extended warranty" package. That can add many thousands to the price.
I have an uncle who paid several THOUSAND dollars for a dealer rust-proofing package (including a few re-applications), and then sold the car before it was even 8 years old! (In which case, why did he even bother? It didn't add several thousand dollars to the value of the 8 year old car!)
