2006 Nissan Sentra Sedan SE-R 4dr Sedan (2.5L 4cyl 4A)
Disappointed
 I totally agree with Carolina (first page.)  I had a Sentra in the 80's never changed the oil, did any maintenance or anything.  Ran like crazy.  Now, I totally maintain my 2006 that I bought new and it has had belt replacement, thermostat replacement, heat plate adjustment, and now until it warms up it sound like it's going to fall apart under the hood.  Also, the cup holder is too close to the stereo controls.  It switches from radio to CD when you bump it.  The gas mileage isn't the greatest either.  I won't buy another Nissan.
