Average age of Mopar Maniacs.

I"m 60,1st car 69 340 swinger,my friends and I have a conversation about as the enthusiast for a certain era of car age and pass on,do those cars become less sought after?does the value of them decrease?I"m not up on the market of model A's and T's but a large number of those people who had one for a 1st or 2nd car have passed,considering swings in the economy,various condition ratings of cars it would be difficult to say there is less demand or value of a model A today vs 15 years ago,but if I were to take a guess I think both are diminishing.Drag racing is another subject we think is dying,cost of modifying or building a car today is so high its out of reach for most young people,even spectator participation is low watching a televised event and they pan the stands,there empty,maybe its always been like this but I was too busy to notice.My 2 cents.
