that's how the darker color cars should've come from the factory!!
when i bought my Z, i was going to buy the graphite metallic or the black, but due to the weirdness of the titanium colored door handles and the hypersilver wheels the sport came in, i went with silver at the end. plus, the silver had 3 or 5 miles on the odo and still wrapped in plastic.
in fact, my Z is still wrapped in plastic.
