Glad I was fortunate enough to have a c6 z06 for a few years. With so many speed cameras unless your going to a track it’s hard to enjoy the full potential of many cars. At 180k I would rather have the c6 Zo6 second hand as could not justify the extra cash vs performance you can’t really use. I took my car to a specialist as thought it had a problem which turned out to be it was trying to loose grip at 120 mph. That was enough power for me .
