You were wrong about a lot, not just one thing.
Where did you get the number of 100 still left? Like I said, I've been into M-bodies for a long time and as far as I know there isn't any verifiable information as to how many might be left.
And here's the truth: if you didn't think the car would sell, then why take the time to present it in the manner you did? You were hoping a sucker would come along, hear the word "Mopar" and drop the coin.
As far as the rest, welcome to the world. If you're wrong, rather through error, lack of information, or outright lying (which is what you've done with the claim of 100 left) you're gonna get called out on it.
Too bad if you don't like it. The next time be more honest and actually learn something.
I'm more than willing to teach someone who wants to know about these cars. I've done a lot of it. But starting off in the hobby with no knowledge of what you own and then trying to bullshit people about what it is? No.
