My 1999 Nissan Sentra has been a great car. I use it to commute to work and school. I have been getting great mileage. If you are familiar with the Bay Area, I can make it from San Jose to San Francisco and back on only a quarter tank of gas. This is a very comfortable car.
The stereo is great, but it could use more bass.
The only problem that I have experienced is the failure of the passenger window's motor.
