2003 Nissan Sentra SE-R Spec V SE-R Spec V 4dr Sedan (2.5L 4cyl 6M)
Worst Car I've ever owned.
 I purchased this car brand new in April 2003 and owned it for 3 years. It was nothing but problems for those 3 years straight. The catalytic converter failed within 2 months of owning the car and had to be replaced. This happened 3 additional times over the 3 year ownership. About 2 1/2 years in the engine blew all by itself and had to be replaced. The alternator failed multiple times and sometimes the car would die while in motion. The car had many rattles/creaks all over it always. The transmission developed many issues and grinds and had sounds like loose metal inside of it. I have read many problems with this car from others as well. Stay far away from it, its an endless money pit.
