2005 Nissan Altima Sedan 3.5 SL 4dr Sedan (3.5L 6cyl 5A)
Unsatisfied after 3 years
 I just traded in my Altima after 3 years and 57,000 miles because of a few fairly large issues in my opinion: 1) Loud Road Noise 2) Rough ride over bumps 3) Replaced front breaks at 35,000 miles 4) Replaced back breaks at 45,000 miles 5) Replaced bent rim at 35,000 miles 6) Replaced battery at 56,000 miles 7) Very wide turning radius  If you want a FUN car to drive, this car will do it for you.  The 3.5 engine is simply unbelievable.  It's also a very attractive car.  However, if you're looking for ride quality, steer completely clear of this vehicle because you will be very disappointed.
