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.
Interior design, AWD performance in snow, nice torque at higher RPM, reasonable maintenance costs, bulletproof reliability, great style for a 4 door sedan, led taillights, all the tech gadgets are superb especially the nav and bluetooth, just a joy to use, audio system easy to use and quality
Needs an extra cog to improve mileage, CD changer at top of trunk limits usefulness of trunk, 3k service intervals seems conservative, seats and paint wearing quickly
