Doesn't that mean that they should just raise the price? Flippers mean there's uncaptured value.
Congratulations, you've captured the maximum possible value... from one sale.
If you want to sell 1,000 vehicles, unless you're willing to have a salesperson wheedle every single buyer out of the maximum amount they're willing to pay, rather than just doing some market research and setting a "reasonable" price, there will be uncaptured value in 999 of those sales. But you'll probably make more money, with less work, in that scenario.
