They're just following the business plan of Porsche. Get less for more but at least Camaro has door handles and a cowl over the gauges
Damn dude....did you really just draw a comparison between a Porsche and Camaro?

A Cayman S starts at ~$64K. And there is a hell of a lot more to the driving experience of that car than a Camaro can dream of. They are in two completely different classes.
All that said, I do like the freshened up Camaro much more and the Z28 package looks sweet. BUT...I would pay no more than $40k for one...on a good day.
Nonetheless, I doubt GM will have any problems selling them.
