I bought my 02 Sentra with 25 miles on it. I now has 140,000 and has only seen the shop for tires, brakes, and oil. It gets wonderful gas mileage with the 1.8 L 4 cyl but the car is light weight enough that it is peppy and fun. The only downsides are the seats are not that comfortable for long rides and it could definitely be quieter at highway speeds.
7 speaker stereo, quick, reliable and great gas mileage.
Lots of road and wind noise at higher speeds. Seats are not that comfortable for long trips.
