If ever your shopping either a 2001 or 2002 z06? I'd say decide up front if your going to keep it internally stock. If you are then go for the 2002 z but if your planning a few internal mods then the 2001 is a hell of a deal.
Good luck as the c5 z is definitely like driving a race car on the street.
Half a decade later and I'm still smiling every time I'm driving this thing.
Got up this morning at 4 am and half the motivation to head over to the gym was the drive in the Z to get there and back.
Bottom line is dropping a mild aftermarket cam and headers in a 2001 Z is not a bad way to go.
