To the OP. Just enjoy it and be careful. Just because you have a fast car doesn't mean you have to drive fast everywhere. I've learned that over the past couple years since I've had my Z.
Sure, the first couple months after I got it I would 'get on it' and have a little fun with it, but that's just because it is the fastest car I've owned, and my first v8.
I still goose it every once in awhile when I feel a need for a rush, or want to hear the beautiful sound of my 346ci LS1 through my Flowmaster Super 40. But, I do this when no cars are near-by.
Just be careful and enjoy it.
