Having owned 2 older Altimas I'm disappointed with my new 09 Altima 2.5S 6 speed manual. The engine sounds horrible when cold. Acceleration is not good when trying to merge onto the highway but its ok around town. The cheap plastic door panels vibrate way too much when playing the music loud (very annoying). There is too much wind noise. The drivers seat is not comfortable. I hate the handling. The cheap tires and soft suspension makes the car floaty and unstable. On the highway the car is all over the place especially on windy days. Ironically it corners fairly well. On the good side, the ride is nice, it has plenty of room, it looks good and it gets great fuel economy.
