All you have to do is look at the corvette pricing structure and you can see that the Z/28 is gonna reach $80k. The Z06 hit's 80k easily and then you make the jump to $110k for the ZR1.
The LS7 and the brakes alone are a $30k premium over a 1LE and we haven't started talking about the new wheels/tires and seats etc.. it's going to be a pricey Camaro so get over it.
Now in response to the OP, the Z/28 will give you sensations that the refined Z06 won't be able to approach..
