C6 Zr1 launch date 2009, still putting these new generation tt mustangs and gt500s on notice. I think the c5 and c6 are the best bang for the buck right now.
Well may I ask 1 thing. What about C7s?? Is it like C6s are better than C7s? Why did Chevy downgrade?? See the matter f fact is.. The C6s biggest advantage is its shape and its weight. 1 f the most slippery designs with such a damn light weight chassis.. Alsmost as light as a Ford Focus sedan while packing in 800+ whp and an aerodynamic shape. It will b an embarassment if it isnt this capable. Any car with such light weight and shape and having over 700-800 whp is gonna b insane. The best part f C6 is that its Manual is incredible and complements its power well
