The M35 is more luxury-oriented as compared to the G-series. It's not really the ideal candidate for "performance"-minded folks, but just about anything you can do with the G you can do with the M. It all depends on what she is looking for. If she likes the ride and has no interest in cornering harder, focus on the engine. The VQ has a lot of power already, but can be expanded even further with plenty of aftermarket support. If she wants to corner harder, suspension can easily be modified. First try to determine what she's looking for, then check out the G35 forums, a lot of information would be applicable.
