A 3500lb weight would put in classic Muscle Car territory.
I'm not too worried about design changes because I'm thinking Chevy wants to continue selling more cars than the rest but when I read all the whining that went on because of the tail light improvements on the
'14-'15 models I can only imagine what's coming in May. If you already have an earlier model and think it's the Cat's Meow then keep it but models do change over time save for the old VW's and perhaps the 911 Porsche which remained the same forever. Keep up the good work Chevy!
