I think I have become a Mopar snob

I wouldn't call it being a snob. Just opinionated. Opinions are subjective. The 50yr old might have used insurance money from his wife's passing to buy what he always wanted to have. One never knows all the bits that make up others' experiences. The term "frame off" has come to mean more than the technical realities of each unique model of car. See how many Mustangs have also had "frame offs"....
In terms of snobs and frames... I have a Chevelle. I bought it to flip, but found so many things to be below my opinion of good that I couldn't sell it and feel good about it. One of them is the patches and issues with the frame under it. One inquiring guy called me a snob. Because I told him of the laundry list I felt it needed and he felt "none of that is really that big a deal." We disagreed... But I'd wager the issues would have been a big deal when talking dollars...lol.
So I'll be a snob. And when it goes for sale it will be what I consider "right" and if he wants it, he'll pay.
