2006 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl 4A)
I love the Nissan Altima
 This is by far the most fun sedan I have ever owned.  I got the special edition and I love it!  Even for a four cylinder, its extremely powerful.  It is the most powerful 4 to date over its competitors at 175bhp.  Gas mileage isnt that bad, at about 22.8 mpg.  I like this model over the revised 07 model.  One of the things that make the altima great is its astronomically large rear seat.  I am 6'4'' and I am very comfortable back there even with the seats moved all the way back.  Highly recomend as a used car!  Even to buy over a new one.
