 Really there isn't too much to complain about this vehicle. Absolutely bulletproof reliability. Peppy motor combined with an above class grade interior. The wood is beautiful. The gauges and LED accent lights reflect a designer's touch.  The car truly needs one more gear though which I believe Infiniti subtlety acknowledged by engaging the transmission in the 08 model. I've driven both cars and prefer the 08 for this change alone.  Aside from the mileage, which is frankly poor (I average 18mpg), and the need for an extra gear, the engine does have to rev to make you feel like you are driving a true sport sedan. Furthermore, the trunk space is limited by the CD changer. In sum, super car.
