in the 18 months I looked, there were exactly 3 black 6sp sport non-touring to be within 300 miles of philidelphia, baltimore, and virginia. When i was ready to buy there were 2 on the nissan site (which is the worst site ive ever used).
When I was ready to get mine, the dealer called the first place, it was sold that morning. They tried for ~2hrs to get ahold of someone at the second, and they just couldn't get anyone there.
They cut me a deal on the Z i have now, and i'm actually glad i got what i have.
Yes the nissan site is TERRIBLE, but sometimes you walk in and they make it worth your time
good luck!
