I bought this car used with 43000 miles. Almost 8 years later and at 143000, the car still runs great. Has always started up. It has only required basic maintenance (oil changes, tires, brakes, lights). It is a stick and gets 30mpg in town, 35 mpg highway. I'm so satisfied with this vehicle, I'm looking to get another Altima.
Reliability, reliability, reliability.
Emissions. The light for emissions is on and will have to get fixed the next time I get inspected. This seems to happen to all the Altimas.
