It is Metallic Slate Gray, which I think was out for 2010-2012. I have only seen it on the 370Z, and maybe a Titan. I'm sure they put it on other stuff, but they nixed it for 2013.
The options I was looking for were:
Black leather interior
Sunroof
4 cylinder with auto (CVT)
Gray
No spoiler
Bose without NAV
I was actually looking at all years, but preferred the 4.5 gen. Glad I held out, because this one is it. I was quite pleased when I saw the 'reliability poll' on the other thread because the 2010's are a 'good year'. It only had 25,000 miles on it when I bought it last year, which was way low compared to other coupes. It has almost 30k now.
I'll get the transmission done at 50-60k like everyone recommends, and then just drive it forever. After a few years it may get dated, and then I can shop for some body kits.

I want to keep it stock mechanically, though.
