 I've had this car for not too long, but so far I love it.  The only problem I've had was the battery dying, but that was not the car's fault.  Whoever put in the battery put it in wrong.  After the battery was put in properly, has been running perfectly fine.  This thing is only a 4 cyl yet has a lot of power to it and corners like a dream.  My mom has a maxima and it has horrible turning radius, the Altima is a little better but could be improved.  It is really responsive.  Everyone complains that the car is too noisy, but I love the noise it makes it sound beefy, I even want an exhaust on it.
