0 chance they would go with the 67-69 look
if they want it a Chrysler Cuda works just fine...its just a name....
if they are just going to tweak the Challenger body to a 1970 Cuda do you think they could get another 8 years out of the exact same body? at some point everyone who's going to buy a car will have bought one...you cant keep making the same car for 16 years (8 years Challenger/8 years cuda)....
i dont doubt they will do it.....maybe 2013-2014 and then call it all quits
