I didn't buy the 370Z because of the HP, I bought it because I like the car and the Heritage/History of the Z.
Yes is not a perfect car but is the best bang for the buck concerning Sport Cars. Some of those issue can be corrected easy.
The only part that makes me mad is that Nissan knew about those issues and did nothing to correct them pushing it to the customer.
However, if you do not track the Z you should not have any braking or oil cooling problems.
C&D and MotorTrend Magazines are always bias and will pick up any muscle car over the Z, even the damn Genesis Coupe.
So what ever they write about the 370Z I wipe my butt with it...
