In my opinion only, the Super Sport with a 427 is likely not worth much more than the Super Sport 396. The RPO package is what gives the Z24 SS427 it's value besides the fact that there are many VERY expensive and valuable parts on the Z24 that are not on the Super Sport. Having one of each of the 3 years and each body style adds even more value.
Mr70, are you crossing over to the dark side now or what?
