Rarity does not necessarly mean value when it comes to old cars. If the car is in number 1 condition,restored to the highest standards with no expense spared, always trailored, kept in a climate controlled environment year around and is an open car. It might, on a good day bring 85 - 100 grand depending upon the auction and if the right buyer(s)are out there. Also, supurb original unrestored cars with very low miles will sometimes bring top dollar.
