Hi guys.... just wanted to offer my 2 cents.
As some of you know, I just recently purchased my 2010 PW Z. I love her. I owned a G35 coupe before that as well. Prior to buying, I spent about 3 months researching and test driving. It all came down to 2 cars (as far as NEW cars were concerned...ended up nixing getting a USED something): The 5.0 and the 370. I test drove all the versions. The GT coupe and the vert, and the Z coupe and vert. I went back 3 times because they were so close. I was looking at price, performance, handling, and looks as my 4 criteria.
Performance-wise, the 5.0 had the Z hands-down. I was almost going to buy the 5.0 on performance alone, but I had the Z winning in the other 3 departments. My "boy" side was all about speed... but I wanted the "whole package" so to speak. I think what tipped the scales for me was my wife... I had her in all the cars we drove, and she just thought the 5.0 was "ok". But when we saw the Z in the dealer lot, I won't forget her saying to me "Now THAT is a good looking car".
She also gave me food for thought that made me buy my Z the next day. On the night before I signed the paperwork, she said, "I saw an old lady in a mustang convertible today (turns out it was a 2008 vert). Is that going to be how our car looks in a few years??? something an old lady drives???"
After that comment, I was dead set on the Z... no regrets. Moral of the story: the women in our lives give the best honest and unbiased opinions
The 5.0 is a GREAT car, don't get me wrong. But it wasn't right for me. Shape and looks can't compare to the Z. Again, just my OPINION.
