Owner of 1937 Custom Berline Cord looking for info to help sell

[Dawn_Hume]

This is my first post so hopefully I am doing this correctly. I am helping the owner of a 1937 Custom Berline Cord gather information to help sell his car, where to start how to get fair value etc. He is the second owner and purchased the car in 1947. It is in original condition and has 64,000 original miles. I am aware that there are very few of these cars left and we have one of them. Any information would be appreciated. Thank you,
