The Z outhandles the Mustang, but like I was saying, not by much. Stock for stock the Mustang will beat the Z on any track (save for maybe an autoX), it just won't put up the skidpad (.97 vs. .99) or slalom numbers the Z does. That's really it.
This is a
very surprising car.
I said it before and I'll say it again. The 370Z reminded me a lot of a previous Mustang I owned. The Z to me is kind of like a Japanese Mustang... almost always the underdog and almost always exceeding expectations.
Both cars are excellent values and both cars take the fight to much, much higher end products. I'm lucky to have owned both.
