I found a 1964 1/2 Mustang Coupe for sale. I am trying to figure out what the actual value of the car might be. I checked the VIN number and it checks out as a '64. 170 engine with single barrel carb, 3 speed stick. The serial number is 200767, which translates down to 100,767, a very early car. It has gone through 1/4 of the restoration process. It needs floor pans and some trunk floor work. Most of the interior is still there. Can anyone help me? Thanks.
