You can get 2 to low 3 figures al day as the world is full of car wash businesses who likely make enough to fork out $xx or low xxx for a good name.
That said, reach out to the larger ones who popup in Google search first. Even some might want it for their domain name collection etc.
I think you'll likely get low to mid $xxx if you find the right buyer, but I also wouldn't be surprised if you got more (private sales happen all the time which we don't see in namebio etc, and it can be names like these).
So general market value based on .biz sales, $xx to low $xxx. With the possibility of a fair bit more if you get lucky.
