Personally, I don't feel the PW hides the lines on the 370Z at all. On my last car(2008 Mazdaspeed3) I chose a Gray over the White because I felt the white hid the lines on the Mazda but mostly because the car had very sharp lines compared to the Z's rounded fenders and more flowing lines. The pearl white has just enough flake in it to highlight the fenders and and not let them blend like a flat white would.
Photos do not do it justice and if you haven't seen one in person I definitely recommend going to see one. White does not always photograph the best since the flash takes away the contrast. If you are looking for a car that looks good in a brochure than pg is prob the best since it is one of the more metallic colors.
I don't regret my choice at all, and I get compliments ALL the time on how nice this color looks on this car. To each his own so choose what you like. Either way the 370 looks sick in any color!
Here are a few pics of mine but I say check one out for yourself as well. Good luck!
