All that show and go from the factory. You would have to completely revamp the Z to get it to accelerate, brake and track like the ZO6. You would spend a lot of money and if you decided to sell the Z you would never get back what yo put into it. The Z06 on the other hand, if left stock, would hold it's value better and if held for the long term could fetch collector car values far in excess of what you paid for it.
