I though about selling..now im thinking of cloning it.

'76 factory sunroof with a factory 360 I haven't ever seen one like that. Not a lot of '76 Dusters around in general. They were throw away cars, ran hard, rusted out, junked, wrecked, not here anymore. Chrome bumpers, rally wheels or dog dish hub caps, get it running good, detail it up, make it as stock appearing as possible I think it would be a lot more appealing.

Wasn't that long ago '73 and up cars no one wanted. That is changing because the values of the earlier cars are getting out of reach for a lot of people now. I think the later cars will ride the coat tails of the earlier cars over time. I would not be in any hurry to get rid of it if I were you. And if you do sell its near guaranteed your will ever be able to get another one like it ever again. Join the ranks of "I use to have a" and "I wish I would have never sold" crowd. Once its gone its gone you are not going to be able to get one like that ever again. You won't realize what you have until after its gone.
Yes,A body cars were the poor man's mopar.. That's why the producers of Married With Children gave Al Bundy a "Dodge" (it was really a Duster). It was something a "shoe salesman could afford". Back when that show was made those were dirt cheap transportation. Nobody wanted them and you could buy them for peanuts.
Supposedly the fastest appreciating segment of the collector car market is now 1980s and early '90s vehicles. Those cars are skyrocketing in value. Jay Leno has done shows on the subject and referenced the 200k plus 1993 Toyota Supra with 500 miles on it and a 93 Fox body mustang that sold for over $100k. To me those are cars that aren't even worth owning, but as Jay Leno pointed out the demographic is changing and the people who remember and care about the 50's and 60's cars are aging out of the hobby and divesting themselves of their collections and the younger people are now going after the cars they wanted growing up and either had and sold or wanted and couldn't afford.
It's the same thing with all the "oldies" stations that used to play 50's and 60's music....now they are playing nothing but 80's and 90's cra....stuff. lol. There was a time when an even older generation was collecting and restoring model A's and T's...
