I've had my G35S for a couple of weeks now. I'm still being easy with it until I get past the 1200 K mark. So far the car feels pretty strong, but keeping it below the prescribed limit doesn't show you much. Still, very smooth and I'm certainly not disappointed. I'm still trying to find a rear spoiler and that doesn't seem to exist. I want plastic, not fiberglass. Can't wait till I get past the break in.

 

Congratulations man! I just joined the Infiniti world last week. Post some pics!
