I know the major differences are the increased HP and toruqe. Any other major differences? Is the navigation screen a "touch-screen" or the manual button navigation like the G35?? I heard that there is a capacity in the screen where I can store files/songs? Any detailed description? thanx

 

as the owner of an '07 G35, I can tell you that the navigation on the G35 is indeed a touchscreen.

And yes, the nav system includes the music box, which allows you to rip CDs to it.

 

3.5L vs 3.7L
5sp vs 7sp Auto
Switch seat heater vs **** seat heater
$$$ vs $$$$

 

To add:
1. Side view mirrors are different
2. B/w an '07 and '09, the '07 have 2 overhead ambients while the '09 only has 1
3. The Sport Package Journey/6MT have the Akebono BBKs as well as the new split 5 spoke rims

 

Also:

09 has scratch shield paint.

Sport package Journey/ 6MT also has the quicker steering ratio from the G37 Coupe (to compensate for the uglier wheels!)

 

ROFL!!!

I was wondering what the trade-off was.

I'm hoping Infiniti puts on some decent Sport package wheels in '10, so I don't have to waste a bunch of cash on aftermarket rims when it comes time to trade in my '06.

 

Question: I've seen the G35 sedan wheel chart. Does the G37 have the same limitations in wheel widths as the G35? Or can the G37 take on much lower offset wheels without any guard mods?

 

Wheel fitment is the same as far as offsets and sizes. The exception is the brakes on the Sport models. They require a lot more room to clear, so the wheel selection is greatly reduced.
