You should quit CFZ asap, that's going to keep you away from moving your order. I bought my car in April-2014, place an order for 2015 Z51 wit couple of options including CFZ, my order was stuck at 1100 code till January 2015 and that's when my dealer told me to quit that option or I will wait for who knows how long, so I did cancell CFZ option. Last Friday my 2015 VY Z51 was build and I have my VIN and waiting for shipping. My dealer told me if I keep pushing for CFZ I will be waiting at 1100 still. Instead I bougt carbon fiber ground effect from C7 carbon, way chipper and better looking.
