Z06 broke again today sitting at a stop light. 2800 miles on the odometer. Won't be able to have it towed in till Chevy until tomorrow as their service department closed at 6pm EST. It seems to be something serious though. The engine refuses to idle, refuses to start without throttle, throttle response had about 1 sec lag, it shakes ferociously back and forth about an inch in either direction, I think I may have broken a motor mount, not sure though and the transmission makes a really loud metallic clinking noise. We'll see what diagnosis they give it tomorrow. This was the tip of the straw for me, Gallardo next most likely (even though I am also considering a Murci, but it's a bit more than I really want to spent).
