I've driven a ZO6 for a few days before
buying the NSX. Here's a comparison:
The Z06's steering is too light No feel.
Shifting is truck-like. Body rigidity is worse
than my 11 year old Honda. Ergonomics are
pathetic. Controls vintage 1970. Build quality
poor. Wavy panels, uneven gaps.
Acceleration and braking are much better
than the NSX. Handling is about equal.
The Z06 feels half sports car and half truck.
The shift feel is horribly coarse. This car feels
like an old rattly crapbox with a big engine
stuffed into it. There is none of the hi-tech
feel one gets from most modern cars. Sure it
costs less than a new NSX but I don't see
the attraction at all. You get what you pay
