I believe that driver skill and self-confidence have a lot to do with this particular comparison. I drive my '02 Z06 daily with a much higher confidence factor than with the SPF. Something can be said about the roof over my head, traction control, ABS, better brakes, low profile tires, etc. all contributing to that. The SPF is
fun, makes lots of beautiful noises, pulls incredible in all gears and is fairly predictable in the corners with the Goodyear Billboards. But it's not set up to handle freeway exits at more than 2X the posted speed limit like I can do all day long with my bone stock Z06. I simply don't have the pocket book nor the
huevos to explore the limits with the Cobra like I (sort of) have with the Z06.
The driving experience is more excillarating in the Z06. The
journey is more fun in the Cobra.
But, then again, you can drive the Cobra like you stole it and the exhillaration factor goes waaaaay up.
As always, your mileage may differ.
