Either way I am getting off my soap box since most of you don't want to face the reality of the market.
I think the reality of the market is that right now things are very slow, and the market is full of buyers who want a freebie. If you HAVE to sell, you are probably going to be disappointed by what you get. But if you are NOT a desperate seller, then buyers may be disappointed too.
The Ferrari market is a good example. Beginning of last summer, Challenge Stradales were 180k. Lately, there have been cars that have sold cheap (low 120s); desperate sellers, and/or cars with issues. That's brought out a bunch of potential buyers who thought "wow, I'd buy a good CS for 120k". Well, most if not all are still looking. And they are often a little irritated. "Why won't they sell to me for 120k? That's the going rate!" But in fact, it's not. The folks who have good cars and don't have to have the cash in hand are not selling that low. But the market is slow, and cars are not moving often at $160k, and again the buyers say "but see, you have not been able to sell the car for 6 months because it's priced to high. You need to be realistic about your price!" Fact is they are realistic: they have a price that they will sell for, and if you don't like it hit the road.
The GT40 market is even more confusing, because there is such a spectrum of cars. You have SPF cars that people bought without putting a minute of their own effort in to, and you have replicas that people have invested years of sweat equity. As a buyer, you cannot say "the market says this car is worth X" and expect to close the deal. The market is not just what the buyer will pay, but it is also what the seller will take.
if you are a potential buyer, ignore emotional investment at your own peril. Someone I know moved to town here and found a house they liked. The owners had lived in it for some 50 years. They had the house priced a bit high. The person low-balled them. The sellers were so insulted by the offer, the reply was simply "We will not be selling our house to you. Good day." Which was too bad, because they wanted the house, and lost out on a opportunity by trying to "get a good deal".
