This reminded me of Finnish folk racing Jokamiesluokka[1], where the owner of the car has to entertain offers for the car after a race and must sell the car if there's a willing buyer. This is to keep the cost of cars down.

This is similarly done in American short-track racing as well with the “engine claim” system - I’ve normally heard of it on dirt but I wouldn’t be surprised if asphalt series do it to.

Below is just one example of how these rules can be structured.
