I, for one, would grab whatever AMC kit that comes out. I owned a '77 Hornet AMX hatchback when it was new. Would love to see that in scale!
The AMC cars, to me, were certainly as interesting as anything GM put out back then.
In my stash, I have Ambassadors, Rebels, Americans, Pacers, Gremlins, Javelin AMXs, even the '59 Wagon. I just have no Hornet (too costly these days).
I believe a newly tooled kit would sell well. The original kits have hefty pricetags on the online thing.
I'd buy a whole lot more of a new AMX kit than I would a brand X that's been re-issued umpteen times!
