The Mecum Effect...Part of the Problem...or Part of the Solution???

I have a 1971 383 4 speed Dodge Challenger Convertible(originally came with the fresh air system ) which i have owned for about 20 years. I saw one that sold on Mecum for 199,000.00 which was not even an original fresh air system car, are people nuts? My car has value to me but who would expect prices like that.
