2004 Nissan Sentra Sedan 1.8 4dr Sedan (1.8L 4cyl 5M)
Has some issues but not too bad
 Very common problems that will cost you a lot of dough...crank sensor problem, evaporation valve problems...  Those are the main 2 I know.  other than that I like my sentra, but don't know if i'd buy another nissan based on the massive number of Nissan owners complaining of these two problems, which I call defects.
