While I am a big fan of the unique AMC styling, I really can't see it happening. The AMX, Javelin, Matador and Ambassador were like no other.
It would compete with and overlap sibling models which is something that Chrysler-Fiat still can't really indulge themselves in right now.
The Eagle brand was marketed and dropped. Nostalgia sells to those who care to remember good experiences with these cars.
Good business decision? Probably not.
