One other thing to consider. Using a 39 year old car as a DD comes with the insurance risk of being totaled for a minor fender bender. As a DD, your friend will need conventional insurance rather than stated value or collector car insurance. As such, keeping the total cost of ownership down is the most important thing. Food for thought.
