About 500 miles ago my "Check Engine Soon" light came on and I had it diagnosed. Turns out it is only the O 2 sensor which is kind of costly, but isn't an immediate problem to deal with. Other than that my Nissan drives like it's still new.
When I went to buy a car I knew from the begining that I wanted a Nissan, but I never thought I would be able to afford it. But I knew the finance manager from the dealership and he gave me the car for a price I could afford. Since that day I have become ever more greatful for the car. It is extremely reliable very quick stock and decent on gas. I couldn't be much more happy and do not regret that I will be paying this car off for the next five years. The sentra is a great car, but I recommend the se 2.0 or the r-type. I hear the 1.8 liters are a little weak, but have never driven one myself. My stock sentra can easily beat any stock civic cavilier sunfire focus or most other compact cars. You are slightly limited in modifications, but this car doesn't need much. If your choices come down to a sentra or any other compact car you are better off with the sentra or the civic solely based on reliability.
I own a 2001 SE and I have to say it is not limited to Mods look up SR20DE RR on google you will find a million different mods for this motor, its one of the most famous Nissan engine blocks and a great all around motor, plus it get around 30mpg!
