Model A's are still worth a pretty penny, i've seen just the cab go for what you could sell a running A body for. As far as your car goes, if you don't care, the family members don't care enough to take it over than sell it to someone who will care. A new quarter is less than 400 bucks(plus whatever whoever welds and does the body work charges), the non repro'd parts like the fenders seem to be in good condition. As far as "10's of thousands or that style" being built, count how many 67-69 Mustangs and Camero's you see on the road than count how many A bodies total you see.....
Like I said if you look at it as an investment and could give a flying damn about it sell it to someone who will. They're rare but they're no retirement fund, us Mopar guys are a rare breed, and it's no vanishing point Challenger.
