There are 1001 used car sellers, and Let's say the value they give is $0, $100, $200, $300, ... , $9900, $ 10000(that is, their willing price).
There are many buyers who value each car higher than its current owner. For example, a car worth $3700 to a seller is worth $4700 to a buyer. In this case, obtain a balanced price. In other words, look for a price from the buyer's point of view that they think they deserve to buy based on information about the seller they have.
