We all could just save and buy Porsche Cayman S and Boxster S. They are loght, quick, and safe in crash test ratings!
And refering to a previous comment up above I thought the new 370Z lost weight over the previous model? That was what made it so special!
I for one think the next gen of Muscle Cars: '14 Mustang / '15 Camaro will be lighter with smaller engines with either forced induction whether it be smaller V8's or even V6's. This could be the last go around for the GT500. The new GT might have a forced induction V8 which leaves no need for a GT500 if it is lighter than the GT now. I just hope the SS and GT don't end up getting V6's with forced induction, just yet, but it may be innevitable!
