2001 Nissan Sentra Reviews
Once a piece of this car breaks in the engine it causes a cascade of broken parts, so make sure to get it fixed right away. Often have to buy parts right from dealer, and they're expensive!!
Bought this car with 8,000 miles on it. I have done all the regular maintenance (oil changes etc.). Now it has 160,000 miles and still runs like a champ. Most dependable car I have ever owned. Only negative has been that silver paint recently began to badly oxidize.
