I live about 10 minutes from the old Camaro/Firebird plant, it broke my heart when they closed it. GM and Dodge can try all they want (and I can respect a new Challanger (no pun intended) and Camaro) but the mustang is an american icon, that's why it's survived 40+ years throughout gas hikes. Dodge will always have the General Lee, but the Dodge lot near my house has 8 chargers in the parking lot (I pass them everyday on my way to work) and they haven't moved in 3 weeks, wheras the Ford dealer couldn't keep a single mustang on the lot when they came out because everyone was buying them up.
All in all, if GM wants to go for it, I'll be pleased. I liked the 60 & 70 Camaros, I just don't think the Camaros have the "allure" of a mustang that will drive sales way up.
