My thoughts,
There is no denying that 40K isn't a lot of money. But really it doesn't go far either. Thirteen years ago I bought a new ford truck that was 40K and today I still have it, maybe it's worth 10K I don't know. Nine years ago I bought the wife a new Toyota SUV that was 40K still have it and today it might be worth 10K if we are lucky.
Someone buys this cool classic D/Dart. It's a rare low numbers factory special race car. Similar to a Shelby Mustang of the day or even a later COPO Camaro. But because it's a Dodge we think he or she paid to much and is stupid or a idiot?
Someone else said it already, doll it up like that Hot Rod article car and drop a few magazines around it for probably very little money and a car like this could hit a home run. Or just restore it to original. Were the parts that exotic that they couldn't be found or replicated for minimal cost compared to those other two cars I mentioned, I don't think so?
Correct or not the D/Dart is a pretty special car, or at least I think it is. That one doesn't look half bad in the pictures. Hard for me to imagine the buyer getting hurt on it. Or at least any worse than buying a new car today and driving it for a few years. Not many new cars on the lots these days I like that are 40K or less.
I still think the smart money is on these rare cars if they can be bought right. Those are my thoughts and by the way I didn't buy the Dart and I don't know who did. But I do usally buy high and sell low :-D
