Yeah. If you can't buy another truck because they aren't selling them anymore, then your 12 year old truck is worth a **** load more than you think it is. Or think of it this way, if YOU are trying to buy a truck, but no one will sell you one and YOU have to have one, you are likely overpay for that 12 year old truck. See how that works? Suppy and demand. Economics 1113 my friend.
Yes availability of a resource does impact value. But what impacts price far more is perceived usefulness and cost.
Here is what any buyer asks:
How long can I use the resource? What can it do? How reliably will it function? What is the total cost of ownership?
There will be huge skepticism that Model T-R can function as well now as when the model "only" had 100,000 miles on it. It's well known: The TR Transmission could blow at any time.
And the cost of ownership is high even were the Cowboys to trade Tony for a 6th rounder...because his salary will be hard for teams to absorb in the salary-cap landscape.
One more thing: there is no football equivalent to collector model cars and trucks.
Yes a trade could theoretically happen. But even for a late round draft pick...Jerry will be hard pressed to find buyers because of the age, condition of the model and the existing note to the bank coming along with the asset.
