How rare is this and what's it worth?

I'm not looking to make money off of this car, this is literally my DREAM car! If I were to aquire it, it would be mine forever. I was just merely looking for a ballpark figure on what to expect for a asking price.

As far as the interveiw process, I think the old guy wants to make sure it goes to the right person who will preserve this gem for what it really is. I myself can't possibly imagine a more perfect mopar combination. My valiant project has sapped all of my disposable income lately, and I hope I can scrape up enough cash to snag this project of a lifetime. Ill keep yall informed on how it goes, I'm gonna call the guy here shortly. Ill try to get pics if I can.
