 I've owned my Altima for a little over 2 years now. PROS: Good engine response and pedal feel. This car drives much better than its Toyota and Honda competitors. This car feels spacious and definitely has more comfort room than many other competitors such as the Chrysler 200. Fuel Economy is pretty good. CONS: Upholstery does not come in black, so it won't match a black interior option. There seems to be some unintended ventilation in the foot well when air flow is directed to the windshield. There is some BSR (Buzz, squeak, rattle) from the bracket housing the speaker(s) behind the rear seats during bass-heavy music. Headlamps are adequate but could be improved for better luminosity. There is some wind/road/transmission noise when on the highway which can get annoying - can be drowned out with music but we shouldn't have to do that. The Navigation system could use improvements with the interface and operation - When a turn is coming up, a lane suggestion would help so we know which lane to turn in. Also with Navigation, give a heads up on 2 incoming turns instead of just the immediate one, and let drivers zoom out on the map when getting close to a turn (Currently, the navigation goes into zoomed-in screen showing the turn - which helps - but won't let you look at the map until the turn is complete).  Lastly, I got the underbody lights option for the car (lights up the ground next to the doors so you can see where you're stepping during night) - These need a more robust method of attachment to the vehicle. Salt from winter roads makes these loose and non-functional. OVERALL = This model is very capable in performing as a vehicle but it could use some help with noise cancellation and elimination of BSR. I think the CONS for this car are small improvements that NISSAN should be able to easily capture. If they can address these issues, then I think the Altima will be superior to all its price-bracket competitors in the sedan segment.
