I look at it this way... A totally restored 1979 Trans Am would be about $18,000. If you made the car into a "clone", then you loose some value because you are not going back Original, but you are making it more desiarable by making it what people want. So, if you Clone the car, I would put it at about $18,000. So, going back to original or making it a clone would probably net you about the same amount in the end.
