2004 Nissan Sentra Sedan 1.8 4dr Sedan (1.8L 4cyl 4A)
No problems here
 Bought my 2004 Sentra 3 years ago and I love it.  No problems whatsoever.  Its a no frills car but it is a great commuter and gets excellent gas mileage.  Ive seen some of the complaints and I guess I got one of the good ones.  CD plays and the car just humms along.  My kids never complained about the size of the back seat but they are kids.  Very happy with car.  Very inexpensive too.
