Market value is what a buyer will pay. 2 buyers bidding creates the actual market value even if everyone else doesn't participate.Bring a Trailer prices are outliers. And that is the case in every marque forum, and I watch several different marque forums and BaT. Its is an auction format and you get two people in the room who almost always pay more than market value by 5-15%. I've been buying and selling cars a long time. On every type of vehicle, lots of mods do not get people nearly the cost of the mods back on sale. That is simply a determination of the market. And on mainatnce history, it goes hand in hand with mileage. A 300k miles truck with good history with not be similar in to a 100k miles in value. Its a balance of miles and history.
