Regarding the ZR1, I have mates who have worked in engineering and R&D with GM... It may have done an extraordinary time but it took like 7+ ltrs and a mega diet to achieve this BUT most importantly it is built like crap... He didn't work on that particular car but the build quality at GM is so bad that dispite being a fan since childhood, he now refuses to buy their cars having worked for them... Kind of explains their predicament in the US today with bankrupcy... You may do a 7:25 today, but you'll probably be unable to complete a lap in 5 yrs time. When they can build a ZR1 that can do it all day, everyday.... I'll gladly embrace GM too...

 

That´s unfortunately telling... I am a fan of the C6 for its performance and character, just not sure, as you said, how it will hold up in consecutive use. I would love to find out from the forum´s C6 owners (that are hopefully still present). Smiley
