Practically Speaking, What is This Car Really Worth?

What would be a fair price in today's market (for both buyer and seller) for a vehicle like this nice '65 Valiant convertible. Obviously (for me) the asking price of $19,995 is a little high. Maybe someone here has sold a similar car in the recent past? Thank you.
