How do we value our cars?

In general what I see is that $5,000 buys a really good original early A, no rust and very road worthy. Maybe another $1000 ( so that's $6,000) for a really nice Formula S. There may have been a few cars at auction that get a bit more but not too many. So there's a large gap between what you can buy and the value guides. To me this means if you can get all of the agreed upon value it should be taken. Then if you want you get another car for $6000, in all likely hood a better example too, and then there's enough left to do some upgrades. The one exception would be if you have a deep emotional attachment, say if you or soneone I the family is the original owner, then I might want to concider getting it repaired.
