63 Sport Fury 383 4-speed, what's it worth?

[69L78]

This belongs to a friend of mine, it is a low mileage 2 owner car black with red and white int. one repaint factory bucket seat 4-speed 383 4 bbl. Look at the Hurst sticker on the dash and the tach. The sticker reads Warning This car equipped with Hurst Floor Shift, Shift as Hard as You Please But Don't Break Your Arm.
