I drove a 2003 Nissan Murano, and thought the FX would be a step-up. Ride, styling, handling,I think the FX is better. But, some features and comforts, the Infiniti is not as good as what should be it's lesser sibling. The back seat is much smaller and less roomy. For the driver comforts - the window controls are poorly placed, the HVAC controls are not as easy to use as the Murano, and there are none of the great storage compartments of the Nissan. Two real disappointments: a fresh air vent that routes through the engine compartment in a way that blows hot air regardless of outside temp, and a built in bluetooth handsfree phone microphone that is horrible-all callers complain!
styling, responsiveness, anything to do with driving/handling. The back up camera is handy. The keyless feature is also convenient.
HVAC temp and fan speed controls like the Murano. More storage compartments. Cargo area cover should be standard. A high-end vehicle like this should have an audio input in-dash for an ipod, etc. Even Chevy Blazer has this. Do something about the horrible handsfree bluetooth microphone.
