There are some that are sold out in theory and will never get past that this isn't 1975 anymore. I find this in our hobby with the older (I'm getting there myself) folks that had something instilled in them 40 years ago and they go ballistic when a thought challenges that doctrine. Here is a prime example. I had a 1954 Ford Crestline for sale in my front yard. And old gentleman caught my wife at the Post Office and said "what year is the Buick in your front yard". My wife said "that is a 1954 Ford". He got stern and said "I know it's a Buick, that's from my era blah blah blah blah". She politely said "it's a 1954". Smiled and walked away. Why? The old stubborn crow was set that NO lady much younger would tell HIM about those 50's cars. LOL.
