All dealers will adjust their offers regularly based on their inventory levels of like vehicles, trends of how long it took to sell a similar vehicle and what the profit margin was, and what comparable vehicles are selling for at auctions. Also, some dealers use Carfax and some use Autocheck, which means a "negative" history report that shows up on one but not the other may also influence an offer's value. Our 2019 Beetle showed "minor front damage" on Carfax, but showed nothing on Autocheck. We got higher offers from the dealers that used Autocheck, for example.
