I was looking to purchase a C6 Z06 one of the last NA V8 manual cars. I saw an immaculate 2009 with 4300 miles. The car was stunning in Machine Silver so much so my wife who isnt a car person thought it looked fantastic. I am 6'1" and really couldnt fit. I felt like I was in a tunnel and really didnt have much headroom. and the seats truely felt like I was on a couch. I was pretty disappointed. They had a C7 Z06 and I think it was worse. I am not sure why GM cant get it right but I dont think 6'1" is exceptionally tall.
