That is a perfect balance between cost and enjoyment. $10,000 is more than fair. Love this car. Worth every penny provided all things are true in person. You get to own and enjoy a time capsule, take to shows.
This is rare to see, but is the poster child of why it is not worth it to buy a "project" car for $2500 or $3K. ALL KF project cars not called Darrin, or maybe convertible, should be $500 cars, more or less. Otherwise, be patient and look for these.
