The Z's steering is slightly numb, but it still has better feedback than most cars. Definitely better than the C6 Corvettes I've driven and about even with my Sport-package Mustang (with sport mode engaged).
Of course, you will be tainted for life if you ever test drive something like a Cayman S.
That car (the base Cayman, anyway) is the 370's benchmark and, for the price, Nissan did a great job coming up with something that gives it an honest run for its money.
When I first was looking at a sports car I was looking closely at the 370, Cayman S, and Corvette C6.
The C6 had the power, but lacked refinement and an interior worthy of its price tag.
The Cayman S had a wonderful balance of power, incredible handling and feel, and quality. Unfortunately a new one cost more than a new C6, and a used one still cost more than a new 370Z.
The 370 had a great balance of power, handling, and feel with a great price tag to boot. Sure it wasn't as fast in a straight line as the Corvette, but it had a better feel and a higher quality interior, and no, it wasn't as refined and didn't have the feel as the Cayman S, but for $35k vs $40k used or $60-70k new, none of that really mattered to me anymore.
The 370 is a great car. I don't care what anyone says. If you like it, buy it. It WILL make you happy. Enjoy the thing for as long as it makes you smile. Owning a Z is great experience.
