Sentra owner 
2008 Nissan Sentra Sedan 2.0 S 4dr Sedan (2.0L 4cyl CVT)
Nissan good or bad ?
  I've had my Sentra for 16 mos. and I am not happy at all. The engine is NOT quiet. I was back at the dealer after one month. A noise came out from the engine like  a valve opening and closing under pressure, very loud. They (dealer service) said that is not a problem until the check engine light from board is on!!   Still I have that noise. And is a very lazy car for 2.0l engine. Inside is poor quality, immediately scratched up from just the belt.  I'm very disappointed with my Sentra.  Also I own a Nissan Quest and this one is very smooth and quiet car.(even if I had some problem like water inside the trunk... and shaking doors,  dead battery after 3 mos). Think twice before you buy!
