2002 Nissan Altima Sedan 2.5 SL 4dr Sedan (2.5L 4cyl 4A)
Stay Away!
 I bought this car after saving money for two years. As a college student, my commute only involved going to college and back, and work almost everyday. The car started giving me problems from the day I bought it. Cam/crank position sensors, which had already been replaced before because of a recall went bad. Had to pay $400. The head gasket is faulty in these models. Consumes more oil than gas. Ac/heater problems. Suspension has issues. The backlight for radio stopped working. Its a very fragile car. Unless you love wasting your hard earned money, don't buy this car, even if it is handed to you for free. Its a complete piece of junk!
