Z06 cons:
1* Cheap interior parts
2* Interior leaves one absolutely cold for a car in that price range - one winter then one summer and you start having plastic parts fall apart (I personally witnessed this during a Z06 test drive last fall)
3* You are one wipeout away in turns if you gave more gas than needed - yes it will happen!
4* Monstrous power, why is it a cons you might ask, go back to point#3 + cops on the lookout for you.
Z06 Pros:
1* Power
2* More Power
3* (More Power ^2) + (1/2 ZPower) + (Extra Power)
4* Will scare the sh*t out of your pants power
5* Will make your heart race through turns as you ask yourself if that specific turn is the one you wipe out at and lose the car. Please check youtube videos for that.
6* You don't have to deal with civic ricers as much, they know how sh*t will go down if they try
That about sums up. Have fun!
