Can anyone help with the value of this car?

You can play that family thing too far.If he gets others-like the ones on here-bidding on it,you can kiss your nephewism good bye.If it is a car that you like and would drive,offer him a descent price.You have heard what most agree that it is worth.Play the poor nephew too much and I guarantee that you will be sitting on the sidewalk,watching someone else drive off with it.Nice car and I would love to have it.6000-9000
