2007 or 2008
Jeff, methinks you'll be happier with the 5AT. I like the 3.7, but the 7at seems mis-matched to the engine with all the gear hunting (based on extended experience on dealer loaner vehicles).
I do have to admit, though, fuel economy was a noticeable difference. My regular commute (no highway) I normally averages 18.3 mpg. Same commute/driving style in the G37 yielded 21.6. On the highway it was cruising about 700-800 less rpms for the same speed.
I had a loaner G37 last week and agree with the gear hunting. It was rather annoying. For performance and response, I like the 5AT better.

Hopefully some of the newer trans software TSBs will make the 7spd more decisive, sure hope so!
The improved mpgs (especially highway) and slightly better acceleration on the loaner G37 is what really gave me a bit of buyers remorse after getting my G35. Plus, the loaner 37 had no sunroof and I had tons of headroom! I didn't even know G's came without a sunroof!? (I'm 6'7" so it is an issue for my crazy height!)
That loaner was crazy fast---I'm guessing because the ECU has learned to accept daily beatings as a loaner, and without any options like a sunroof, premium package, etc...weighing it down, I'm betting it would've pulled an impressive run at the local track!

They should have just put a nice overdrive cog on the 5AT, Keeping all the
5ATs good points but having the heavier overdrive for good mpgs. The 7AT
is kinda like Payton Manning, it's great for the most part but shouldn't overthink the job at hand

0-60 the G37 is just a bit quicker since it's got 22 more hp, something like a 10th of a second, not sure about the 1/4 mile difference, shouldn't be much at all.
