2003 Nissan Altima Sedan 3.5 SE 4dr Sedan (3.5L 6cyl 5M)
Wooooo Hooooo!
 I bought my '03 3.5SE brand new.  I knew I was going to buy it as soon as I turned the key and heard that "vroom!"  I have put 83,000 miles on it in 3 years and have not had a single mechanical problem. My check engine light came on one time but just because I left the fuel-cap door open, it was very expensive to have the computer re-set. The plastic latch on the center console broke three times, minor nuisance. At idle it sounds like a Jetta but when you get it over 4,500 RPM the sound is knee weakening.  Over-all an extremely reliable car.  I would recommend this to anyone.  I just saw the re-designed 2007 model and am planning on trading this one in soon.
