I bought my Altima as a demo with about 3K miles on it and 4.5 yrs later at 110k miles I havent had any trouble with it. I had to replace the battery and the brakes which are normal maintenance. The car is very dependable. When I wash it it shines up just like new!
For the price it has some nice features. The 4cly engine runs like a 6! Leather 6 way power heated seats woodgrain accents 6 disk Bose system. Its a nice roomy car! Mine is actually a 2.5 SL
The styling of the 2008 is better and I love the new 2 door.
