2002 Nissan Altima 2.5 SL 4dr Sedan (2.5L 4cyl 4A)
Purchased this car with 56,000. Soon discovered what others have been talking about. Prepared myself for the worse and at 90,000 the catalytic converter self destructed. Caught it in time and replaced with new. Shortly thereafter the head gasket problem surfaced and the transmission needed to be replaced. Far more repairs than one would expect from Nissan. The engine problems should be addressed. There are better cars out there.
