2010 Nissan Altima 2.5 S 4dr Sedan (2.5L 4cyl CVT)
Got the car 3 months ago with the SL version. Love the nav system and the Bose stereo. Noticed the same problem as Alex B with the bass. Even at 0 level and treble at 3, the back ledge by the rear window does not hold the bass. Probably needs more padding to damper the vibration. Looks like very thin shelving for speakers and subwoofer location. Besides that love driving it. Gets good mileage for both city and highway. Live in N.Y.C. and getting 20/35. Not bad compared to my 96 Murano. Only downfall is none of the cars come with some pkgs. You have to get all, meaning all the pkgs are connected to each other. Adds a lot more to base price. Got windows tinted, looks great.
