I think it is a little odd to talk about sports cars in terms of 0-60. It could be just the way times are changing. I certainly had no interest in drag race quarter miles when I went Z shopping. Of course I don't track the car. In my view the Z excels in:
- Plenty of power to accelerate in spirited driving.
- Wonderful handling at any speed I dare drive (so far that is 110mph)
- Easy and forgiving in evasive moves. An 18 wheeler didn't see me in the left lane and nearly ran me over. But the Z responded instantly to an 80mph hard left to the shoulder.
- Lots of fun to drive.
I wouldn't add any power bolt-on's. It's fine for me as is. I did add a backup cam, SS brake lines and DOT 5.1 fluid, and a very good radar detector.
