Smile on my face
 I have had this car for 6 years and I still can't get over how much fun it is to drive.  I rented a Corvette on vacation and couldn't believe the difference.  The Z is fast, refined and nimble, the Corvette was fast, loud and didn't handle as well as my 1961 Corvair.  The only car I have seen that would make me want to trade it is the 2010 Z with the twin Turbo.  That has to be scary fast.
