This is an old thread - but I'm new to Camaro ownership. I test drove both and could have afforded the SS. Maybe its just me, but I could feel the weight difference - the M6 just seemed more agile in a croud.
I was concerned about the power output, but left enough burnouts now to be sold on the M6. Of course I will mod for more power. If I can get close to a stock SS without the extra weight I'll be very happy
An honestly - this is the first car I have owned that I don't see selling, pretty much ever.
