I had an '02 Altima 3.5 SE, and have now upgraded to an '07 3.5 SE. My gas mileage with the '02 was about 10% higher, especially on in town driving, and moderately higher on the highway. Are there any
Are there any upgrades that can be added to improve the mileage. Generally the car is built better than in '02, although the Bose system is a little weak. Ride is better, and the appearance is better although the headroom in the back seat is reduced from the '02. The '07 runs quieter and seems to be much more solid. A fun car to drive!
